How can people record in movie theaters and get away with it?

About a week ago I went to go see zootopia (a really good movie by the way) and during that movie I look over to see someone recording the movie with their iPhone, I knew because he didn't turn the brightness off all the way, and when we got out I was going to tell the manager that someone recorded in the theater but I didn't there was no cop cars outside the theater so he got away with it, how do people record in a movie theater and get away with it?

Who cares?
And right there's why.

They get away with it because people who see them (like you) don't report it to the theatre.

Because people like you don't report them.

Lol, sulking because somebody watches a movie for free. Ooooh the injustice. Lmfao get a grip.

Stop being an ugly lil rat

They get away with it mostly because nobody catches them in the act and when many people do see somebody who is involved in piracy, they hardly ever tell
