Very interesting.
What I didn’t notice before, is that the perp comes in and shoots the barber point blank.
The guy getting his hair cut ducks out of the way, then the perp WAVES HIM PAST himself, out of the potential line of fire to finish the barber off.
That was just weird that he showed that kind of courtesy for the guy who was getting his hair cut while killing someone else in cold blood.
The irony is in the fact that he didn’t realize he just signed his own death warrant. And as for shooting the guy in the back, there was no time to waste. He was clearly not done and who would take the chance that he’d turn around and make the cop the next victim.
And it wasn’t like the guy was running away so there was no longer any threat. He was going in for more kill shots if necessary.
I also thought that the shooter was going to fire more rounds at the barber. The officer had the presence of mind to check for another potential shooter after putting the gunman down. Textbook!
