I don't expect you to watch this video through to the end, but do watch the first 2 mins. Turn your sound down too.
I believe that the folk in the stopped vehicle were suspected Shoplifters. In the UK, as long as what you've taken is valued at less than £20, then it's no longer treated as a crime. Over in the USA it warrants about 15 cop cars, several motorcycle cops, loads of guns, and at least one police dog. You would certainly be taken off to jail.
Back in the UK, when some little Toad kicks-in your front door, threatens to cut essential bits off you, then runs off with your wife's diamonds; if you're lucky the police will give you a Crime Number (for your insurance Co), and that's it. They certainly wouldn't want to upset the little darling who robbed you. That would be against his 'human rights'.
I hope whatever those people in the white car stole (if indeed they did) was worth all that time, effort, and cost, of all those cops. Somehow I doubt it. I've never seen so many cops just to stop a car, and get the occupants out.
The US cops seem very heavy-handed, and the UK cops are far too lenient. How totally different life is on opposite sides of The Pond. Something in between is needed.
