Tools of Silence

How Criminal Organizations and Governments Use Technology to Watch and Coerce, and What Governing It Requires

A Daylight Project Article

Every factual claim below carries a numbered reference to a source retrieved and checked during drafting; references are listed in full at the end. Claims that could not be verified against a primary or reputable secondary source were removed and are logged in the appendix. This article describes documented capability and documented use. It adjudicates no individual case.

For most of the twentieth century, surveillance was a monopoly of states. The equipment was expensive, the expertise scarce, and the infrastructure — relay towers, interception rooms, aircraft — announced itself. Criminal organizations that wanted the same capabilities had to build them at state-like cost. Pablo Escobar's Medellín organization ran its own radio networks across Colombian terrain and rotated devices to evade interception, and was ultimately located when a U.S.–Colombian direction-finding operation triangulated his prolonged radiotelephone calls on December 2, 1993 [1]. In 1994, counter-narcotics troops raiding a Cali condominium found not drugs but a computer center: a $1.5 million IBM AS/400 mainframe staffed around the clock by four to six technicians, loaded with custom data-mining software that cross-referenced the entire Cali telephone exchange's call logs — leaked by utility employees — against the numbers of U.S. diplomats and agents, to identify informants [2]. The cartel's own head of security, a civil engineer and countersurveillance specialist, later walked that operation into a DEA case and the federal witness-protection program [3].

That era is over, and its ending is the subject of this article. The successor organizations no longer build; they buy retail. A consumer quadcopter, an encrypted messaging app, a burner phone, a satellite terminal, and a data-broker lookup together reproduce, at the cost of a used car, capabilities that once required a cartel's treasury. The consequence for public safety is not mainly about smuggling. It is that the coercion toolkit has commoditized all the way down — to any crew, any rival, any individual with a grievance — and law, as always, is arriving late.

I. What Criminal Organizations Deploy

Unmanned systems, at industrial scale. U.S. Customs and Border Protection detected more than 42,000 unmanned drone flights near the southern border in fiscal year 2025, describing the counter-drone environment as "rapidly evolving, as are cartel tactics" [4]. In congressional testimony, the executive director of the Department of Homeland Security's counter-drone program reported more than 27,000 drones tracked within 500 meters of the border in the last six months of 2024 alone [5]. The military's Joint Task Force–Southern Border has used the Army Multipurpose High Energy Laser to destroy drones it characterized as flying in direct support of cartels; its commander stated that "cartel networks are increasingly employing unmanned aircraft systems to facilitate illicit human-smuggling and actively spy on our personnel and law enforcement partners" [6]. A senior Defense official confirmed roughly 100 suspected cartel drones were shot down at the border in August 2026 alone [7]. Inside Mexico, the Jalisco New Generation Cartel is documented attempting to deploy weaponized drones loaded with C4-type explosives against rivals in Michoacán as early as July 2020, and Mexican forces have seized dozens of drone-dropped bomblets [8]. Reported attacks with weaponized drones remain inside Mexico; this article is aware of no confirmed weaponized cartel drone attack on U.S. soil, and it maintains that distinction because the record does.

Communications built to disappear. The Zetas constructed a proprietary encrypted radio network that, before its dismantling, spanned from Texas to Guatemala through Mexico's Gulf states — hundreds of antennas and repeaters under a series of command centers, used both for internal coordination and to monitor security-force movements [9]. In 2011, Mexican forces razed 167 antennas and more than 150 repeaters in Veracruz and seized more than 4,000 devices across Nuevo León, Tamaulipas, Coahuila, and San Luis Potosí, many powered by solar panels hidden in rural terrain [10]. The network was built in part by kidnapped radio engineers, most never seen again [11]. Today's version needs no towers: in July 2025 the Colombian navy announced its first seizure of an unmanned narco-submarine equipped with a Starlink antenna — an 800-mile-range vessel with onboard cameras, believed to be a cartel test run — following an earlier Starlink-steered vessel seized by Indian police [12]. Colombian researchers report Mexican cartels hiring engineers to develop unmanned submarines as early as 2017 [12].

Data as weapon. The most consequential shift is the least visible. In June 2025 the Justice Department's Inspector General disclosed that a hacker working for the Sinaloa Cartel had, in or before 2018, obtained an FBI assistant legal attaché's phone records and geolocation data, accessed Mexico City's surveillance-camera system to follow him and identify the people he met, and that the cartel "used that information to intimidate and, in some instances, kill potential sources or cooperating witnesses" [13]. Commercial spyware demonstrates the ecosystem's reach whoever the purchaser: Citizen Lab documented in 2017 that Mexican investigative journalists, lawyers for cartel victims' families, anti-corruption groups, and even the spouse of a murdered journalist were targeted with NSO Group's Pegasus, which converts a phone into a remote eavesdropping device; new infections of journalists and a human-rights defender were confirmed for 2019–2021 despite official assurances they had stopped [14].

Revenue beyond drugs. The Treasury Department has sanctioned more than seventy individuals and entities linked to CJNG's timeshare-fraud network — call-center operations centered on Puerto Vallarta that target elderly Americans and "can defraud victims of their life savings" — across at least five actions between March 2023 and 2025, with FinCEN, FBI, and OFAC issuing a joint notice to financial institutions describing the schemes [15]. Treasury's own framing is the point: as the organization "consolidated territory," it "added other crimes to its core activity of drug trafficking" [15]. The enterprise is increasingly a technology and fraud business with a narcotics division.

II. The Switch: From Operations to Harassment

The tools of logistics and the tools of intimidation are the same tools. The encrypted app that coordinates a shipment delivers a threat to a shopkeeper. The drone that scouts a Border Patrol shift hovers over a business owner's house so he knows he is watched. The data lookup that identifies an official for bribery finds a witness's new address. The camera network that tracked an FBI attaché's contacts is the same network that could track anyone's [13]. No retooling is required; the switch from operations to harassment is a change of target, not of equipment.

This matters because the everyday abuse criminal organizations inflict on communities is not the headline violence but systematic micro-extortion — payments demanded from vendors, farmers, transport operators, and families, enforced by ambient terror and, increasingly, by control of legitimate supply chains through coerced exclusivity, dictated pricing, and per-truck tolls that mimic ordinary commerce [16]. The legal system's difficulty with this has always been evidentiary: no explicit threat recorded, no witness willing to testify, local police who may be compromised [16]. Technology has made the coercion cheaper, more precise, and more deniable at once, and extended the ambient-terror model from a cartel's home territory to anywhere a phone number can be found.

Three structural facts follow. Capability has decoupled from organizational scale: what once distinguished a cartel from a street crew — the ability to find, watch, and frighten a specific person — is now available to both. Pressure produces adaptation, not cessation: every interception success taught the market better tradecraft, from Escobar's device rotation to the Zetas' network to unmanned submarines — the same dynamic by which enforcement pressure on bulk supply selected for fentanyl over heroin [17]. And the arms race between enforcement and enterprise is, at bottom, a contest over concealment: every dollar in the record above bought either the ability to hide or the ability to frighten.

III. What the State Deploys

The Framework binds both sides because both sides hold the capability, and the state's side is at least as well documented — often, to its credit, by the state itself.

Behavioral surveillance research. DARPA's Urban Reconnaissance through Supervised Autonomy (URSA) program, launched in 2018 with $22.6 million in first-phase contracts to four performers, seeks "to combine new knowledge about human behaviors, autonomy algorithms, integrated sensors, multiple sensor modalities, and measurable human responses to discriminate the subtle differences between hostile and innocent people" [18]. Its program manager described the concept plainly: a drone "swoops in to deliver a warning message, then observes how the human responds," repeating instructions such as "turn north" and passing the person's responses, video, and location to a human supervisor [19]. The published scenario has an aerial system with a loudspeaker deliver warnings to an individual, re-identify him after he enters a building and exits another door, and release a nonlethal flash-bang to ensure he "attends to the second message" [20]. URSA is a military program designed for overseas installations, and — unusually — it convened an ethics advisory board at its outset [19]; it is cited here not as an abuse but as documented proof that stimulus-response behavioral surveillance is a funded, engineered capability.

Autonomous border sensing. CBP tested four Anduril autonomous surveillance towers in the San Diego sector in early 2018, procured 56 more, and in 2020 made the system a program of record with plans for 200 towers — solar-powered, off-grid platforms whose Lattice software fuses camera, thermal, and radar data and uses artificial intelligence to distinguish humans, animals, and vehicles, pushing detections to agents' phones [21]. By late 2024 the company reported its 300th deployment covering roughly 30 percent of the southern land border, and in December 2025 CBP awarded a $363 million contract for more than 200 extended-range towers able to track objects beyond five miles [22].

Municipal drones as first responders. The Chula Vista Police Department, eight miles from the Mexican border, launched the nation's first Drone as First Responder program in October 2018; its teleoperators monitor live 911 audio through Live911 and launch pre-positioned drones that frequently arrive before ground units and, per the department's own case study, "before the call is even entered into CAD" [23]. By 2021 the program had dispatched drones to 911 calls 3,508 times and assisted in 452 arrests; by 2026 it had surpassed 25,000 missions [24]. Chula Vista also publishes each drone's flight path, duration, and reason for launch on a public website and has committed not to use drones for general surveillance [23] — a transparency practice this article notes approvingly, because it is exactly the Register-and-disclose posture the Framework requires of everyone.

Persistent aerial surveillance. In January 2012 the Los Angeles County Sheriff's Department allowed Persistent Surveillance Systems to fly a wide-area camera aircraft over Compton for nine days, recording the entire city; neither residents nor the mayor were told, a sergeant later explaining that "in order to mitigate any of those kinds of complaints, we basically kept it pretty hush-hush" [25]. Baltimore's 2020 Aerial Investigation Research program — three aircraft, roughly twelve hours a day, tracking movements from crime scenes — produced 1,916 hours of coverage and 6.7 million images before the Fourth Circuit, sitting en banc in June 2021, held that accessing its data was a Fourth Amendment search requiring a warrant [26].

Person-based predictive targeting. The LAPD's Operation LASER, begun in 2011, assigned "chronic offender" risk scores using arrests, gang affiliation, probation status, and field-interview cards — with each police stop adding points — and used Palantir to generate bulletins on named individuals [27]. The department's Inspector General found in March 2019 that the program lacked oversight and applied inconsistent criteria; almost half the chronic offenders had zero or one violent-crime arrest and nearly ten percent had no "quality interactions" with police at all. The Chronic Offender component was suspended in August 2018 and the program ended in April 2019 [28].

The pattern across these programs is the Framework's core finding restated from the other side: the capability is real, the deployment is documented, and the difference between a program that survives scrutiny and one that is struck down or shut down is not the technology — it is whether the watching was disclosed, authorized, bounded, and reviewable. Chula Vista publishes its flight logs; Compton was "hush-hush." That is the whole of Section 28 in one sentence.

The Uncounted Sky

The failure of aerial governance is clearest where the density of unmanned flight is highest, and Southern California is the densest case in the country.

At the lowest altitudes, municipal police and fire departments fly under separate local authorities. The LAPD's Drone as First Responder unit — a pilot from July 2025 until it became a permanent unit on August 13, 2026 — averages roughly 23 launches a day from rooftop docking stations and logged more than 3,500 deployments in its first year [31]. Municipal DFR programs reportedly operate in Santa Monica, Beverly Hills, and Redondo Beach [UNVERIFIED — AB 481 audit], while Culver City, Burbank, and Pasadena maintain tactical fleets for high-risk operations, Pasadena's limited to four SWAT drones with no DFR program [UNVERIFIED — AB 481 audit]. Above them, the Sheriff's Department runs a countywide Special Operations UAS fleet restricted to tactical, search-and-rescue, hazmat, and disaster missions, and the city and county fire departments fly thermal drones to active incidents [UNVERIFIED — AB 481 and municipal reports]. Federal Customs and Border Protection crews work the coastal corridors [21]. Higher still, NASA flies earth-science radar passes over the basin and the Navy flies high-altitude maritime patrols offshore [UNVERIFIED], while the experimental tiers — DARPA autonomy programs, Air Force and contractor test flights — operate not over the city but in the adjacent restricted corridors of the Mojave: Edwards, China Lake, R-2508, and the offshore ranges [UNVERIFIED].

The strongest defense of all of this is real and should be stated first: almost every one of these programs is episodic by policy. The Sheriff's drones fly tactical and rescue missions only. Fire departments launch to active incidents. The LAPD's unit does not patrol; it responds to dispatched 911 calls, and its cameras activate on arrival [31]. Nobody in this inventory is authorized to watch a neighborhood.

The finding is not that the aggregate constitutes centralized surveillance. The finding is that no authority aggregates the total. Every program is separately authorized, separately logged, separately governed — and the cumulative airspace over a resident's home is nobody's jurisdiction. In a region with dozens of public-safety and federal air operators, the LAPD's flight dashboard appears to be the sole public transparency portal [31]. A resident who watches something hover over their street at two in the morning has no registry to ask what flew, under what authority, or why. Not because any single agency refuses to answer, but because the question crosses a dozen jurisdictions that each answer only for their own piece.

Except in one place, where the aggregation already exists. The municipal programs run on private infrastructure: autonomous quadcopters and docking stations from a single hardware vendor, video and telemetry flowing into commercial evidence clouds, license-plate and tracking platforms whose software links records across agency lines [UNVERIFIED — vendor contracts and city procurement records]. Departments that legally cannot share a database can share a vendor. And the transparency asymmetry is exact: California's AB 481 requires agencies to publish their equipment inventories and hold public hearings on what they own, while the algorithms that process the footage, the computer-vision models, the retention parameters, and the cloud architecture remain proprietary corporate property. The public may learn how many drones a city bought. It may not learn what the software does with what they record.

That is the fragmentation thesis in physical form, and it is what Schedule A.35's Technology and Surveillance Register and Section 28.4's disclosure rules exist to close: one verifiable ledger, open to oversight, in place of a maze of separately-counted flights and privately-held aggregates.

IV. Why Law Arrives Late

The Supreme Court held in 1928 that wiretapping was not a search [29]; it reversed itself in Katz in 1967, and Congress regulated wiretaps in Title III the following year — decades after the practice began [30]. Compton flew in 2012 and Baltimore in 2020 before the 2021 ruling [25][26]. LASER ran for eight years before its own Inspector General ended it [28]. Government regulates surveillance after the damage — and the same lag governs criminal use of the same tools, because statutes written against specific devices are obsolete the day the device changes. A framework that writes late is worth little. A framework worth anything writes early, against effects rather than devices, binding everyone the capability reaches.

V. What the Framework Provides

The Operational Standards and Transition Framework treats the technology problem as a governance problem with two sides.

It governs by effect, not by device. Section 28 defines "Surveillance Capability" and "Autonomous System" by what a technology does, so a capability is covered the day it exists rather than the day it is litigated [§28.2]; the Lag Clause makes novelty no defense [§28.11]. Section 27 defines a "Coercive Demand" by its effect on a reasonable person in the affected community rather than by its medium [§27.2], so the note on the counter and the message containing a family's address are the same conduct.

It binds both sides identically. No party may use any surveillance capability to identify, locate, track, or pressure a complainant, witness, victim, worker, monitor, or journalist [§28.3(3)] — the clause the Cali mainframe and the Mexico City cameras exist to justify [2][13]. No autonomous system may take adverse action against a person without an accountable human decision [§28.3(5)]. No one may be made a research or calibration subject without documented consent [§28.3(2)]. Government may maintain no person-based list or designation without notice, a viewable record, and a way to contest and exit it [§28.4(2)] — the LASER lesson written as rule [28].

It names the quiet coercion as Red Line Conduct. Floor tax, coerced exclusivity, dictated pricing, transport tolls, forced property transfer, displacement, and demands for silence are Red Line Conduct whether or not they resemble commerce, and a demand's coercive character may be established by pattern, context, and reputation [§27.2–27.3]; compiling personal-data dossiers to make such demands is prohibited at the preparation stage.

It closes the reconnaissance channel and registers everything. Mapping the coverage or blind spots of any oversight function is itself Critical Breach conduct; acquiring interception equipment, spyware, or covert trackers is a breach on acquisition [§28.5]. Every surveillance-capable technology any party uses is entered in a Technology and Surveillance Register open to the Independent Monitor [Schedule A.35] — the Chula Vista practice, made mandatory for all [23].

It gives the harassed a channel and an examination. Intake runs through the Monitor, independent of any local agency, with anonymous reporting and no obligation to testify [§27.4]; complaints of technical abuse go to independent accredited forensic examination against verified baselines, with findings reported honestly in both directions and the absence of examination never cited as evidence of absence [§28.8; Schedule A.36]. Protection follows risk and need rather than belief, and no complainant is screened out solely because of characteristics the alleged conduct might itself have produced — while no allegation is presumed true because it was made [Credibility-Manipulation Addendum].

It ends the war over concealment rather than joining it. Section 28.9 states the structural point the record teaches: the technological contest between enforcement and enterprise is a war over whether records and communications stay hidden. A governed enterprise, whose records are truthful and lawfully inspectable by right, has no lawful use for concealment tradecraft; a governing party, receiving disclosure by right, needs no covert penetration of what is already open. Encryption protecting records from unauthorized access is required; concealment of records from lawful oversight is prohibited. The two are opposites, and the Framework never confuses them.

VI. The Honest Scope

This article has confined itself to what the record documents and this draft could verify: industrial-scale border drone reconnaissance and, inside Mexico, weaponized drones; proprietary and now satellite-linked criminal communications; data-driven targeting of officials, witnesses, and journalists; commercial spyware; the fraud economy; and, on the state side, funded behavioral-surveillance research, autonomous border sensing, municipal first-responder drones, persistent aerial surveillance, and predictive person-targeting. It describes no capability beyond that record, because a framework caught overclaiming loses the only currency it has.

That evidence is sufficient on its own. A vendor who pays a floor tax under a drone's shadow; a witness whose new address arrives from an unknown number; an FBI attaché's contacts harvested from a city's own cameras — none of them needed exotic technology to be endangered. They needed only for the tools of ordinary commerce and ordinary government to be turned, without modification, toward fear. The Framework's answer is to make those instruments worthless: name the coercion regardless of medium, bind the watchers on every side, register the tools, examine the complaints, protect the harmed without demanding they first be believed, and end the secrecy every one of these technologies was purchased to protect.

Silence allows abuse. The technologies in this article are, every one of them, technologies of silence. Daylight is the answer to all of them at once.

Appendix — Verification Log

Removed for lack of verification (do not restore without a primary source): fiber-optic communications installed in smuggling tunnels (no DOJ/CBP release located confirming this specific claim); "parasitic" antennas installed on legitimate cell towers (the verified Zetas record is of self-built antenna networks, not parasitic installations); Norte del Valle Cartel's contracted electronic-warfare specialists and real-time radar-gap mapping (widely repeated in secondary accounts; no primary source located — the 2004 D.D.C. RICO indictment of NDVC leaders is real but was not retrieved to confirm these specifics); "1,000 daily unintercepted transmissions"; cartel use of generative AI in fraud operations (plausible and reported generally; not verified for this article — the Treasury record documents call-center fraud, not AI tooling).

Supplied citation list — audit. Of the citations supplied for this article from an external AI source, the following were verified as real: Bowden (2001); Rempel (2011); OFAC timeshare releases; Olmstead, Katz, Title III; Leaders of a Beautiful Struggle, 2 F.4th 330. The following could not be verified and appear to be fabricated or mistitled and were not used: "DHS Office of Intelligence and Analysis, Unmanned Aircraft Systems Threats along the Southwest Border (2023)"; "International Crisis Group, On the Front Lines of Mexico's Drone War, Latin America Report No. 98"; "SEDENA, Reporte de Aseguramientos…"; "CBP AMO, Southwest Border Drone Detection and Interception Metrics (2024)"; "FBI Operational Technology Division, Threat Assessment: Criminal Exploitation of Commercial Satellite Communications… (2023)"; "Logan (2011), Los Zetas and the Development of Narco-Telecommunications, CSIS"; "USAO SDCA (2022) tunnel with fiber-optic communications"; "Citizen Lab, Pegasus in Mexico: Systemic Surveillance…" (real reports carry different titles — see [14]); and, most seriously, the attribution of the Sinaloa-hacker case to a "2023 SDNY indictment" and a "Feuer, New York Times, 2023" article — the documented source is the June 2025 DOJ Inspector General audit [13]. The LAPD OIG report title was corrected to Review of Selected Los Angeles Police Department Data-Driven Policing Strategies [28].

"The Uncounted Sky" — verification status. Only the LAPD DFR program [31] is verified. Every other agency named in that subsection carries an explicit unverified marker and requires an AB 481 pass before publication: California agencies must publish annual military-equipment inventories and hold public hearings, so Santa Monica, Beverly Hills, Redondo Beach, Culver City, Burbank, Pasadena, and LASD are all confirmable from city and county documents; LAFD/LACoFD from municipal reports; CBP AMO, NASA UAVSAR, and Navy Triton operations from federal sources; vendor relationships from procurement records and contracts. Two agencies (Pasadena PD, LASD) were marked "verified" in an external reviewer's draft of this subsection; that tag was not supported by any source retrieved here and has been removed. The private-vendor paragraph is argument built on named-vendor relationships that are individually checkable but not yet checked.

Considered and excluded. NASA JPL's drone program (netted on-campus enclosure; field deployments to Death Valley, the Mojave, and designated test ranges) and the U.S. Space Force (a satellite acquisition command headquartered in El Segundo, established December 2019, with no low-altitude domestic flight role) were considered for this section and excluded: the sources describing them place both outside residential airspace, and including them would pad the roster with entities their own sources exclude. Likewise excluded: any suggestion that orbital systems perform acoustic sensing. Sound does not propagate through vacuum; orbital SIGINT intercepts electromagnetic emissions, not audio; "acoustic testing" in Air Force space documents refers to sound-chamber vibration testing of satellites prior to launch.

Geographic precision note. DARPA, Air Force, and defense-contractor autonomy testing occurs in restricted corridors — Edwards, China Lake, R-2508, Mojave, and offshore ranges — not over the Los Angeles basin. An earlier framing placed these programs in an altitude tier "over LA"; that would be an overclaim and was corrected. The accurate claim is that Southern California as a region hosts the full vertical range of unmanned operations, with experimental tiers in adjacent restricted airspace.

Secondary-source cautions for the publication pass: references [4] and [7] rely on outlets quoting official statements; confirm against the CBP and Pentagon primary statements. Reference [13] should cite the OIG audit document directly. Reference [16] requires specific El País article URLs.
