Real life isn't a movie.

Yeah, well I'm not so sure.

First, the premise is absurd.
A guy gets sprayed with pepper spray, so he retaliates by shooting the person in the face?

Actually, it sounds like a terrible movie. It's barely believable.

Second, this certainly looks like a production.

The camera/video angles and framing of the scenes are far beyond convenient. It looks planned to me.

What are the odds that a photographer captured the incident in the very instant in time where the shell casing was floating in the air???

Plus, the photo is perfectly centered with both peoples bodies completely within the edges of the scene.

The odds of this are probably less than one in a million.

In many cases, people don't just spurt blood.

The head/brain is extremely vascular.
More so, than anywhere else on a person's body.
Blood literally pours out of headwounds.

Also, if the camera captured the shell casing in the air, then where is the blood from the entry wound?

It's extremely convenient that the pepper spray formed a huge cloud at that very instant.

Particularly given the fact that pepper spray actually sprays like a squirt gun, and doesn't generate a huge cloud, which would also affect the person using the pepper spray.

The people who created this hoax must think we're all retarded.

It depends on the situation, and this it seems is one of those occassions

"It seems like" "the victim" was able to catch himself by landing on his backside and falling backwards into a comfortable position; rather than dropping and hitting his head from an instant kill headshot.

Dead bodies lie in uncomfortable positions in real life, but not in the movies.

"It seems like" extremely convenient timing for all of this.

"It seems like" this is a scripted hoax.
