Okay, chances are that this guy is totally wrong, and that his acts were thoroughly detestable and unjustified; but how do we know?
The newspaper leaves out the most critical piece of information needed for the reader to make an informed decision: What was the movie?
If it was a Disney movie or some other family fare, then the guy was way, way out of line. If it was, say, a Tarantino holiday film fest, then the victim should've fuckin' known better.
I'm just saying, actions have consequences.
