From the New York Times:
One man among hundreds of peaceful protesters fired a handgun at police officers in Louisville, Ky. Witnesses caught him on camera.
One would-be cop killer out of hundreds of peaceful protesters is way under one percent unpeaceful. Think about it this way: if there were over 200 protesters there, then the percent who shot any cops rounds down to 0%. Why are you making a big deal about a 100% Peaceful Protest?
