So how many of those do you think were unjustified?
Police in the USA kill civilians at something like
50+ times the rate of other First World countries, so US police are clearly killing far more people (like over 5000%) than can be justified by a First World nation.
The US governments (state and federal) need to fix some obvious problems to bring those numbers down to something less insane:
1. Your police are poorly trained and resort to shooting too readily. Organise them into state-level police forces that have better training, regulation, and support.
2. Your police are scared of your heavily-armed populace. Enact laws to take most of the guns out of circulation. Fuck your obsolete, musket-age Second Amendment.
3. Your police have a military culture which encourages the use of excessive force and abuse of authority.
4. End the war on drugs that has fueled the rise of organised, well-armed criminal gangs.
