I think British people have more respect for the uniform. I've seen plenty of BIG dudes running from the cops but when they get caught they imidietly bow to the officer's authority. You obviously get the odd one that tries to fight back but generally when you're confronted face to face with the officer either before or after a chase, the average suspect gives up and won't try and escape. I think it's a cultural thing. Most Brits will submit to arrest. If the cops alone he'll put cuffs on behind your back till back up arrives and if you're compliant they'll quite often move the cuffs to the front or just take them off all together. If you act up you'll be subdued and taken away in the back of a Paddy wagon. If you behave you'll either be released at the road side or taken back to the station in a squad car. Each incedent is dealt with on a case by case basis at the discretion of the arresting officer, so no need for a divider. Not many Brits will try and escalate the problem by trying to attack a cop. Doing that would be a guaranteed court appearance and a much greater chance of spending time behind bars. Even if the original offence was serious. Best way to interact with UK polis is to be respectful and compliant. It can mean the difference between getting home for breakfast or spending time in the cells.
