Thank God it did, or else a three year old girl might have lost both her parents, let alone threatened the life of the off duty sheriff's deputy that subdued him.
As far as him being annoyed by the texting goes, all he had to do was move to another seat, but no, he wanted to demonstrate his authority like back when he was a policeman.
If the textor had violated any law[s] previously, there was an off duty Deputy in the audience with the authority to arrest him. He took no action. That, in and of itself, says that the victim violated no laws. Now the cover and getting him off begins.
I guess Mr. “I can do anything I want when I want” met Mr. “Oh no you can’t”. Mr.”Oh no you can’t” won.
