By | August 18, 2017

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
