David Dorn is legit.
Berry Perkins occurred at a generally peaceful protest, the type you claim to support. The protestors didn't start the violence.
Dorian Murrell, not associated with riots, looting, etc.
Italia Kelly occurred at a peaceful protest (on the side of the protestors), the type you claim to support.
Marquis Tousan, killed by the police, hardly supports your claim they are decreasing the violence.
James Scurlock killed by violence breaking out at a protest, not a riot. This wasn't in the bar, this was a bar owner acting as a vigilante, provoking violence from protestors.
Victor Cazares is legit.
Patrick Underwood was killed by a far right terrorist assassinating cops, not rioters.
Jorge Gomez was killed at a peaceful rally that didn't turn violent until police started firing tear gas into the crowd.
This hardly supports your claim that the police are preventing violence.
