The national Law Enforcement Division is rarely seen in pursuit of a child with the plague, but when it happens, ifs very very bad.
LEDiv officers are easily the peer of the best in the corporate world, and they have access to everything the government knows, which, ultimately, is quite a lot. It’s just that outside of the LEDiv, the government workers have problems putting it all together. LEDiv usually gets called in when there are other sinister interests involved. Should, say, Arasaka have pulled a few too many snatches in one city, you can bet LEDiv will be hot on the trail, perhaps even setting up deliberate infections for the trapping of the Arasaka team.
Sometimes LEDiv gets involved with pursuing a KidKiller gang. Or sometimes they get called in for reasons beyond the understanding of anyone who lacks a Top Secret clearance from the government. Whatever the cause, they have their reasons, they have the tools, and, with the backing of the government, they can do whatever they want and there’s nothing you can do about it. They move with a cold grace and an economy of motion, and they have no interests other than their own.
Just hope you’re not on their list for some arcane reason.
