Not really. The specific culture of “policing by consent” that is foundational to policing (one of the Peel principles) is still really strongly defended as a matter of policing identity here (as it is in Canada and to a lesser but still noticeable extent Australia). The US police kits itself out with secondhand military equipment from the armed forces. I suspect in some situations this makes them a more effective law enforcement machine but tooling up with military equipment suggests a significant break from Peel principles.

It means that the situations where our police overreact are the situations where they are outnumbered and in confrontation (riots etc.). It means the opposite of them being personally vindictive (though some are and they are depressingly hard to fire)
