When carrying be willing to lose every argument, let cars cut in front of you and back down from all bullies. Never escalate any confrontation.
There is more to this story. Some fodder for thought. The old guy asked the texter to stop. Yes, even though it was only previews. Then he went to see management. When he returned to his seat the "victim" loudly asked if the old guy had "turned him in". Then it got physical. The young guy is a very tall large man. Details of who got physical will come out, I don't know any details. There was only one shot fired which went through the victim and his wife's hand as she may have been pulling him back from the older guy. Stand your ground may come into play here. Stay tuned.
