No, it wouldn't. That is unnecessary hyperbole. Unjustified police killings, instances where the police were at fault, are a rarity. The big problem here is not lack of police training nor overreach, but violent, uncooperative suspects.
>failing to show the correct level of subservience
While there are some grotesque examples of that, like with Daniel Shaver, most police killings, the overwhelming majority of them, are due to them being attacked by someone or being confronted with an armed suspect who refuses to disarm.
>Not saying all of them are racist, but to some police, everyone is the wrong color (not blue).
Are there any actual instances of racism being the driving impetus for police killings at any time in recent decades? I cannot think of any offhand.
