True. And even if the theater had been full of would-be heroes there simply wasn't much of anything that could be done against a guy in full body armor wielding a deadly weapon and who also has the element of surprise on his side.
To everyone: I suggest leaving the second-guessing to instances where people run away from a woman being raped or something of that sort. What happened the other night was off the charts in terms of what any average person should ever have to deal with or be judged by.
