I think this gun-accident video is fake.

The rate-limiting steps are:
- "Who's handgun is this?" sounds too much like an accident waiting to happen.
- The staged-looking gesture when the guy in the brown shirt says you shouldn't put a gun in your pocket.
- The last guy who warns him almost looks like he's setting up someone for a joke because he's smiling too much.
- It doesn't make that much noise.

WARNING: There's a little bit of blood in this one.
