Good thing you were not on the original threads; you would have needed a flame-retardant suit. Let me see if I can summarize:
The texting was during the previews, not the feature The texter was texting his babysitter, not making noise with a game
The theater was a "no guns" zone
The alleged shooter got up to complain to management; it is believed that at this point, he went to his car to retrieve his gun
Seating is not assigned; so he and his wife could have moved seats at any time; instead he returned and forced a confrontation
It was not his place to try to enforce a "no texting" policy
Texting is not a lethal or dangerous activity; it is merely an annoyance that could have been solved any number of other ways, even assuming the victim would have continued during the feature, which was not an issue as the shooting took place during the previews
Witnesses did not hear any loud threats or witness any aggression by the victim other than thrown popcorn; but none of them actually claimed to see the moment it was thrown, or that the victim was the one who threw it
A married woman came forward to say that she had been intimidated by the alleged shooter in the same theater in the previous month when she tried to mind her own business going to the ladies' room
The best thing to do is you are armed and someone is being rude with a cell phone is take the phone from his hand, throw it on the floor and stomp it. Then pull out your gun and say “I hope you’re not too upset.”
