Largely true. It's not that the US police are less abusive per officer or per interaction, it's more than the US does way too much policing.
Just looking at Western Europe (arbitrarily defined, granted, and leaving out some really small countries) in the list at https://en.wikipedia.org/wiki/List_of_countries_and_dependen..., the US has fewer police per capita than (in increasing per-capita order) Ireland, the Netherlands, Luxembourg, Austria, Scotland, Belgium, Germany, France, Portugal, Italy, Spain. More police than (in decreasing per-capita order) England+Wales, Switzerland, Sweden, Denmark, Iceland, Norway.
The US has about 25% more police per capita than Norway. Germany has 63% more police per capita than the US does.
That is not to say that we don't have problems with police brutality or cover-ups here, they are just less deadly usually.
