Neither is true.

He was on his knees with two officers holding his arms, another beating him in the head with some hard item while the one on grey disarmed him.

Only after the person in grey moved a few meters away can you hear a gunshot and then they unload 10 or so shots.

Seems like an accidental discharge or they thought he got his gun in his hand since it wasn't in the holster anymore. Either way, extreme incompetence shown once again by aggressive and untrained white supremacist thugs, which is exactly what they want.
