Opinion | Watch This Protest Turn From Peaceful to Violent in 60 Seconds - The New York Times
On a mild June evening, a large but peaceful group of protesters supporting the Black Lives Matter movement marched toward the East Precinct police station house in the Capitol Hill neighborhood of Seattle.
Minutes later, the march ended in chaos as the police lobbed flash-bang grenades and sprayed the protesters with tear gas and pepper spray. Video of the clash, widely seen online, offers a lesson on how not to handle a crowd. But it also demonstrates a deeper problem in American policing: how officers often double down on a colleague’s decision, with potentially huge consequences.
