I believe that's the case already, Ergo, racism.
If peaceful placards and singing kumbaya really did work effectively , for black people in particular all over the world, we'd have a very different discussion. Police brutality is an extension of the governments very existence - "legitimate" violence - which is turned up to war-time levels when minorities are concerned. All this is smoke an mirrors to the contempt of a man being killed by law enforcement officer in a way that would make Ted Bundy blush.
It seems whenever black people protest, the narrative seems to be of barbarians storming the city gates. An "over-reaction" if you will. Is it? The message of the protest is clear, if a tree falls - the ground will shake. Is that unreasonable?
My main point is protest is what protest does: force the issue. The methods of protest are varied and of disproportionate impact to society. If protest is to succeed, social impact must be calibrated to the received response to protester demands. If no response or negative response is received, increase social impact to belligerent parties and the general public, if necessary. Protest without corresponding social impact is ineffectual at forcing the issue but can be effective in virtue-signaling, which can create a virtuous loop of increasing awareness and support, and increasing numbers of protesters.
