Not sure how we define violence, but I found 2 links that show that in USA there are quite some more police killings per capita than in western Europe.
Of course some killings might be reasonable (very dangerous people, etc.) and violence is more than killings, but there does seem to be some signal there.
The reality and the laws are what people ask repeatedly. Maybe if they don't think it can be different they will not ask.
My reply was directed to someone that seemed to suggest "there is not so much violence".
I think the first step to discuss a topic is to understand what is there. If the statement would have been "I am fine that police in the USA being (potentially) more violent than in Western Europe", I wouldn't have checked anything because everybody is entitled to an opinion. I did check though because I wondered "is it true that there is not much violence in the USA compared to Western Europe?". I can't say I am sure after searching 5 minutes, but it does look like there is a probability that it is the case.
