Looting, burning, attacking others is not a human right.
Nor are they forms of protest. This is not a protest; it’s a riot. These thugs don’t give a rat’s butt about Gray, his death is just an excuse to loot, burn, destroy, and attack cops.
As for communities having problems with the police, it seems only certain communities do.
Then there is the bogus claim about police forces becoming militarized. If cops didn’t have military style equipment and firepower, they would be outgunned by the gangs and drug cartels.
