If three or more of the accused six officers are black, it’s not going to be a simple trial that includes “violated the deceased’ civil rights” with a slam dunk conviction on that charge alone.
If “racism” wasn’t a factor in Gray’s death, but massive incompetence was, their trials will be very complex & messy affairs.
I see several ways this could play out: the 6 cops are all or mostly minority; they are convicted causing riots; or, they are acquitted, with the result that riots ensue; OR, the six cops are all or mostly Caucasian; they are convicted, causing riots to break out; or, they are acquitted, causing people to start rioting
The bottom line is money to Gray's family but nothing else will happen and nothing will change.
