Oh yeah.
Not too funny when someone shoves a fully loaded shotgun to your face either. You get that treatment in the states you say Yes Sir and hope to crap he had his donut and coffee and a good nights sleep. In the UK its all about civility.
The gun and knife craze is happening over here. I feel kinda sorry for them. We just had a special officer (kind of a ride along - not a true cop) get knifed in the neck which nearly killed him while serving an eviction notice. Real scary

down south in London.
They do have a trunchon, but thats for show as most don't know how to use it. Most you will get out of a British bobby is.. Stop...Stop...Please Stop!
They are awfully polite to you especially when the cuffs are on. I see it on TV here, never tried it on for size.
Give a Vegas cop a night stick and he will give you a first class show/beating....
Basically in the US you have a real deterrent. In the UK you have a chance to get a way.
The contrast is amazing.
