An ambulance dog unit! thats the answer! just get an RRU with the rear seats and equipment pulled out and stick a viscous looking dog (or six) in the back. when you get the slack-jawed masses giving you grief its a simple "yeah control, we got a loada scrotes hanging around... RELEASE THE HOUNDS!" Fella on the RRU turns up and the scrotes scarper sharpish. Just gotta get the right dogs. I hear that the dogs used in prisons are the ones too aggressive for the police dog training. We just want a few dogs too aggressive for the PRISON dog training... Yeah I like that.
