According to Independent Mr Long said:
At first it was peaceful protest. Until someone pointed a gun at my head. Then the same person pointed it at my foot and shot the ground.
Another extremist later lunged at Mr Long with a confederate flag and he fought back with a spray can he said he found on the ground, putting a lighter to the nozzle and turning it into a weapon
Is this reconstruction truthful or consistent with the known facts of the matter?
