Against my better judgement I will comment on this, although I am not really taking a particular stance:
In social psych class we learned about experiments done with regards to race/prejudice/violence.
What they found in this one simulation/experiment was that white police officers will shoot a "black suspect" with a greater frequency than a "white suspect."
They also found that black police officers will shoot a "black suspect" with greater frequency than a "white suspect."
I am not entirely sure what this means, but it doesn't looks good for "black suspects."
Honestly (and this is just my gut) I think the "divide" that has emerged in the US is more along socioeconomic lines rather than racial, i.e., a black kid (or any kid, for that matter) simply has a better chance of encountering violence of any sort being in a "poor" neighborhood as opposed to a more "wealthy" neighborhood.
I'm not an expert on this stuff though.
