Assuming your story true (and based on ones I've seen on 'Locked Up Abroad'), I think what happens here is that higher ups are giving the police a win. Everyone in some of these areas is on the take, but the police still need to show arrests once in awhile. So throw some guns and drugs in a house (cost of doing business), put some randoms in there, and call the raid.
