It sounds like the counter protesters were using constraint. BLM needs to calm down.
The counter protesters wearing masks, so what, so were some of the BLM protesters.
The counter protesters wearing bullet proof vests, so what, it looks like they may have needed them at some point.
Just because the counter protesters were there protesting doesn't mean BLM has a right to attack them.
BLM has dissolved into irrelevancy.
The two witnesses describe how the three men were confronted by the crowd for wearing masks and filming the protest. The men refused demands to remove their masks. (Note: the two witnesses in the video masked their faces also.)
One witness says a protester then punched one of the three men. The man then reached for what the protester assumed was a gun as the three men retreated. Apparently no gun was displayed at that point.
The witnesses say the protesters pursued and caught with the three men, punching them again. The men made gestures as if reaching for their guns but apparently did not brandish them at that point.
The three men again retreated and were again pursued by the protesters. The witnesses say they warned their fellow protesters the men were armed and to stop chasing them. The witnesses say they stopped but the others ran after the men and they soon heard gunfire.
