There is an enormous difference between the conduct of police officers between the US and Europe. Again, it mostly comes down to the public’s access to firearms, but the quality of training, institutionalized prejudices, and corrective actions (or the absence of those things) are also significant factors.

The US is not a punching bag. It’s receiving fair criticism and experiencing repercussions for decades of failure to improve public safety, and using both legal mechanisms and populist rhetoric to sanctify gun violence and the persecution of vulnerable groups, leading to a deeply divided, damn near tribal society (Us against Them), and the rise of the American Gestapo under the false banner of immigration control. Be patriotic, absolutely. But patriotism without awareness and due criticism is nothing more than zealotry.
