yes in the US you can wave Nazi flags, but if a police officer stops you for allegedly speeding and you remove your hands from the wheel or look them in the eyes, they can and will shoot you.

They shoot to kill over a thousand times a year.

If any of those EU countries had such stats, they would shutdown the police entirely for abuse of violence.

Fortunately, we are civilized and it never happened.

Anyway you are wrong about the Lodo Alfano in Italy, which I know very well being Italian. The law has been active for a few months before being declared unconstitutional.

I wonder how wrong you are for every other country
