It makes you look twice, but, I believe it is an illusion caused by the camera angle. I believe the man sitting is well behind the shooter's muzzle.






FWIW - a pet peeve:

I can't begin to count the number of times at gun shows and at the local gun shop, I have had to move 'out of the line of fire' of a pointed gun muzzle.

It is not young people.
Old 'Farts', who should know better, are often the culprits.

The hair goes up on my neck and I have to control myself from 'Decking' the offender.

When politely cautioned on the breach of gun safety and etiquette, the response is often a defense of bad behavior, rather than a polite 'Sorry'.
