My mom's dad was shot and killed by police. Absolutely nobody in my family knows anything about it, but the default is "he was a bad person and deserved it" or, "he probably did something wrong." The coroner's report shows his death as a suicide, despite police shooting and killing him. This was a time before cameraphones and before I was even born, so it's impossible for me, let alone anyone else to know what happened.
A lot of how you approach this discussion reminds me of the side of my family that defaults to thinking that the police did nothing wrong, or that their actions were justified or within policy, even without knowing the full facts (or, any; it's willful ignorance out the wazoo), plus a handful of assumptions. And, just -- a person died and that's all you can muster? Callousness and an air of benevolence?
You can do better, friend.
