How many gypsies gets killed per year by police in Europe? Compare that to how many people police kills in USA? There is pretty hard data that European police is drastically less violent overall.

It is possible that European police is more racist than US police, yes, but that wasn't what we were talking about. I'm pretty sure that US police is more violent against white people than European police is against gypsies, meaning that even with the racism European police is still much better.
