Retired police captain kills texter in theater during movie trailer

119. Texting before a movie starts is usually considered okay

So perhaps the old man could have used some manners by not hounding them until after the movie started:

Snip:

Is It OK to Use Your Phone Before the Movie Starts?

Yes. Of course. The lights are up, so who is it going to bother, except the friend sitting next to you who you’re ignoring so you can text your friend sitting on the other side of him. In fact, I often wear headphones and catch up on TV shows while I’m waiting for the film to start because it ensures that no one will speak to me and I won’t have to hear their boneheaded guesses at the pre-movie trivia. When you’re attending screenings of movies like Grown Ups 2, it’s important not to be able to inadvertently eavesdrop on others’ conversations, lest you lose all faith in humanity.

Is It OK to Use Your Phone During the Previews?

This is a tougher call. It’s definitely OK during the pre-movie commercials, but use your judgement during the previews. If you’re in a very crowded theater, I would strongly discourage it. But on the other hand, glaring at someone or asking them to turn off their phone during the previews is also kind of a dick move, too. They’re trailers: Try not to get a bug up your ass if someone’s phone light is illuminated during the trailer for The Smurfs 2.
