Dynamite isn't too hard to come by.
The real question is, who's going to stop them?
Because as far as I can tell, the only people showing up to protect old confederate monuments are David Duke's and Richard Spencer's boys and conservatives can't distance themselves fast enough from them.
I looked up a satellite view of Stone Mountain park. It’s mostly surrounded by wooded areas in which sniper teams could range like fish in water.
They wouldn’t have to kill anyone. When the sandblasters are sent up, a few ricochets off the granite will send them packing. Antifas OTOH will simply be picked off.
Yeah, the entire place will be under military lockdown with drones swarming overhead. But when that point is reached, we are already in Civil War II.
The women, mothers and grandmothers. The left would not attack them because it would be bad optics. When a group of young males show up it fits into the KKK, Nazi, racist narrative but when women show up to protest in a quiet way it would make the leftist look like bullies if they harassed them.
