I'm sure there are going to be some interesting lessons to learn from this sad event.

And my wife wonders why I'm ALWAYS carrying at when we (rarely) go to the movie theater, AND why my head is on a swivel when anyone comes in to the theater. After that incident a few years back in Beslan (IIRC) where a movie theater was taken hostage for a few days, my radar is always switched on. It's a bad place to be with few exits, LOTS of fatal funnels, and no real cover/barriers for protection.
Very sad evening.... I'm relieved that at least they have the suspect in custody.
