It’s worth noting that there is a cultural difference between the US and the UK. In the UK, the police police by consent, rather than police by force. It’s the reason that most police officers are not armed (and went against the government when they suggested it).

The police have a lot more trust than in the US. They are also less attractive to the aggressive power trippers. This limits the rot. They are not perfect, but I know, from friends, there is a continuous game of wack-a-mole going on, to deal with problematic officers, and break up problematic internal groups.

The end result, there is more trust given to the police themselves. They have also shown they won’t abuse it egregiously.
