Look at the way your SWAT teams gang up like a bunch of scare'd'cats, hiding behind each other with guns, shields and hemets.
God, they even need kneepads!
British police do it the real way.
No helmet, face to face with a stick. It's the personal touch. People are less likely to take on the Police if they get beaten senseless in a fair fight.
Your poor victims having coffee were obviously easy pickings. The guy was obviously only worried about a cop with a gun because that is all he knew. Plus your lot are in cars all the time and never walk the streets. If he had had his butt whopped by a policeman without a gun, he may have thought twice about taking them on.
