As the primary unit on scene, you are the one to initiate contact with the robbers, do note that you will need at least one other unit on the scene. When making the initial contact it is crucial not to come off as hostile. Three key questions are asked at almost every robbery scene. Example of how the initial contact may look on a robbery scene.
This Is the Los Santo Police Department, if you’re inside, make yourself known.”
(In very few cases they might not reply if they don’t initiate the breaching procedure).
When the suspect has made themselves and their intent is known make sure they have answered these three key questions:
How many do they have on the inside (Answers may vary and are not always correct.)
If they have any hostages (If so, stress that you will need to see proof of life.)
If they have anyone on the outside. (This will give them a chance to initiate any people that might be outside the establishment and have hostile intent.)
As the primary, it is your task to relay all information to dispatch so all officers responding to the scene are up to date on what is going on. Remember to always value the hostage's life over catching the robbers, a hostage saved is a greater accomplishment than catching the bad guys.
