Every situation is a different situation. We dont have all the details.
Regardless, a human was killed tragically.
I have learned, with a weapon I have a great responsibility in CCW. I avoid situations that can escalate, as I am more aware and cautious.
Based on what happened, I would have left and and or moved to another seat.
Perhaps.
But take out the shooting, and this story has some interesting social aspects:
Why didn't the theater send back someone with the man to check the situation?
And what type of "man" starts a physical confrontation about being "turned in" for being disruptive in a movie theater?
