That’s almost certainly part of the story here. The waiter knew about the scammer. So the bar probably had called the police in the past. Then, as in most cities, nothing was done.
But your comments imply, passive-aggressively, that it was okay to kill the man.
One thing is cleaning up petty theft.
But to commit murder is from another planet.
Planet Retard.
