Because of the 41st constitutional amendment (the one requiring American cops to have fun)

British police actually care about their communities and favour de-escalation over violence since it curates respect and obedience better than otherwise. American cops favour large budgets and shiny toys that go boom and will allow whatever it takes to gain more of them. American cops also enjoy shooting people for sport as evidenced by the majority of police shootings the past several decades. British police have quail hunts for that itch.

I'd like to see you figure out a better way of killing flies, lighting matches, and opening cans of beans. Why, my bike has a little gun mounted to the handlebars that I use to let pedestrians know I'm coming.

Hmm, I’m thinking with guns you can power trip. Without guns, you have to play nicer.

Neither police "deal with crime".

Both protect capital against the working class. Both use violence to achieve this, the US ones are just more open about it.

My mother says, "You got in another po-lice fight?"
Oh, momma dear, we're not the fortunate ones
And cops, they wanna have fun
Oh, cops just wanna have fun ♫

They’ve shown people who carry guns drive more aggressively in traffic. It’s a possiblity cops are bigger assholes when they have guns.

I have spent my 33 years living in the UK.
I've never seen a copper de-escalate anything.

You have to demand they present their de-escalation loicense

I'm not American, so I may be missing some of the historical and cultural context. Still, I worry that the broad availability of firearms, and the political influence of the gun industry, can make violence more lethal and encourage a culture of fear and self-protection. The right to own firearms has historical and constitutional roots, but I believe access should be carefully regulated and that owning a gun should be the exception, not the norm.
