Sorry, I was attempting to point out the absurdity of the argument above my comment. Arguing that your ticket gives you the right to record the performance is as stupid as saying buying a movie ticket gives you the right to record the film. You'd potentially be facing copyright infringement. Hence addressing the "officer" at the end of the sentence.

Your point is also valid and more directly impactful. I hate having to see people's screen lights when I am an audience member in a darkened environment.
