If this was a black cop shooting a white kid, I can guarantee that everyone would've forgotten about it within a week. It doesn't even scream tribal so much if you look at it this way. It's just declaring that black people need attention.
The rioters are very likely just young kids (teens through 20s) who join in the rallies and make off with goodies under cover of all the stink going up.
Also, I-44 @ Grand was shut down by protestors literally two blocks from where my dad works earlier this morning.
