I only recall one - the Autozone guy. Do you have examples of more? Even if you have a few more, they are a small minority of total incidents. Most are true believers.We have multiple arrests of false-flag vandalism.
You seem to be assuming that if an arrested person is white, it is a false flag. But many #BLM and Antifa activists are white.
That does not mean that the two groups do not belong to the same ideological bend (#BLM and Antifa supporters) or that they are not often the same persons engaging in those two activities. Somebody who protests for #BLM at 6pm can throw a Molotov cocktail at 9pm. That does not make it a "false flag" attack or that person suddenly distinct from "protesters".And we have obvious patterns of protesters being followed by vandals.
