Also, your comparison is way off. Not all police departments are the same. Unarmed doesn’t mean “not a threat” or “can in no way be a threat”. I can simply approach you in an angry manner and be a threat. Does it justify death? No, but a three year old?
How much of a threat are the "unarmed law-abiding civilians" in the comment you replied to?
It's just that police in Europe and Asia don't really face dangerous and determined criminals.
That's just laughable. People in the US are not more dangerous than people in Europe or Asia. Lots of dangerous individuals get stopped by police without killing them with 41 bullets. What is more dangerous is the police's behaviour, behaving like an occupying force. US police would also rather kill someone trying to escape from s minor offence than let them get away. Different way of thinking. One values lives above killcount.
