While it's fair to say that bias was a factor in Rice's shooting, and I'd agree, pointing to open carry protests as evidence of this may not be the most effective line of argument. Especially since armed Black demonstrators carried out their own demonstrations not long afterward: https://www.theguardian.com/us-news/2020/may/07/michigan-law...
Police were responding to:
> "There's a guy in here with a pistol," the man tells a police dispatcher during the call. "It's probably fake, but he's like, pointing it at everybody."
The problem with systematic racism is the "percieved threat" part. When I have that racisit bias, I obviously will percieve a black person more as a threat than a white one. I may not even be aware of it, and facing ones own biases is a hard thing even more so for such serious things as racism and police brutality. When this bias is combined with the kind of training US police is getting, it a given to end up where the US ended up.
The only nice thing is, it also shows where to sart to remedy theissues. Once the police and the poluation accepted to see the issues.
