This is obviously a fake. If you've seen enough handgun suicides then you'd be able to spot it easily.
Not to mention the blood splatters before his head recoils. There no fragments in the splatter its just blood. There would be bone fragments, hair, at least something else other than blood. Plus it just seems like to much blood.
You can watch that other video of the guy that really did commit suicide after being arrested and he is near a wall, no blood splatter or anything. He shoots himself, slumps over, and it drains out.
Plus his facial expression goes right to blank. Every pistol/revolver suicide I've seen they usually make some sort of crazy face right after wards.
Like I said, if you've seen enough real ones than there wouldn't be any questioning the authenticity of this.
Damnnnn that hoed the fuck outta all of ya'll!!

AND i agree!
