That's because nobody here has guns (legally) and the police are trained to used them with respect, meaning they're not trigger happy or feel entitled to use them like the U.S. - guns are the last resort for police here.
A gun is a gun, police don't know if it's a toy, a replica, a BB or the real thing. If you wave it about in public in a threatening manner this is the result.
Waving a gun in public and ignoring police orders is asking to get shot in any country
The difference is that you get shot in the US by more bullets (90 aimed shots fired at an unarmed man in LA) than the amount of shots fired by 250k German police officers combined in a year.
And that police officiers only use their guns twice in their career.
