It always amazes me that nobody has thought of the obvious - an armed police force, but armed with fast acting tranquilliser pellets instead of bullets! That way they can drop the criminal and arrest him without killing him. EASY! I also agree that police with revolvers are "unapproachable" - as they are here in Belgium. I once put my hand out to a police dog who was sniffing me and the police officer gave a command in French and the dog turned vicious! I got a terrible fright. Imagine what this officer would do with his gun.
