Hoppah is right, FBI Police is like the Security Agency for large FBI Headquarters, it is sort of like pentagon police, yes? LA does not have a large enough FBI Headquarters for the FBI police to be seen around the whole of LA, Even if there was a large enough HQ in LA, What would be the use of having FBI Police? Because it would be more realistic to let them sit at the FBI HQ where its probable nothing would happen? i mean noone would start a shootout at the FBI HQ, think about it, armed FBI agents in a building, hundreds of them, FBI would win instantly xD
