I would love to read your sources. can you provide them?
The Botham Jeans and Daniel Shavers, as horrifically egregious as those cases are, are relatively rare.
The second question I have is, why are these incidents happening? What is causing these attacks, and why were they armed or felt the need to use their arms? Especially if they keep happening predominantly to black people? There's quite a bit of evidence that when a white person is armed and attacks the police, the police give the guy a break. Whereas when it's a black person, they're more likely to antagonize the suspect and then shoot first.
