I mean, police in both countries can be over-militarized, violent, and racist. That's literally the origin of police in most countries: to coercively enforce the will of the state, usually against working-class and otherwise minority groups
(Also, you must really be willfully blind to think that militarization of American police is an "emotional" statement. It's been happening for decades and has been documented by every newspaper you could care to look at.)
