Just my opinion, don't get your panties in a bunch.
Apparently a baddass entered the the premises with head to toe armor, which i thought was pretty cool. Now nobody would suspect him being a shooter, a lunatic sure, but not a shooter. A lot of people cosplay as their favorite character from a movie, and they wear it as they go see as i saw when i watched that Yugioh movie. I thought dressing up as joker and acting like bane was pretty sweet.
However, i don't agree or disagree for his killing innocents, escaped convicts, future serial killers/terrorists, or even the next Bill Gates. I mean sure there were innocent people in the crowd, but he might have killed some people who might have been related to a bigger affair such as terrorism. The chances of that is low, but it can be. We may never know.
The people in the theater were...wow. I mean really. I read an article where a victim said James Holmes was going up the stairs killing people aisle by aisle. Couldn't the people who didn't get hit run after James and attack him, or die trying? I mean sure you might get injured or die, but you could stall him or kill him to prevent more injuries. Sure there are not a lot of brave people in our society, but at least think of others too, the little kids, or the parents who have to raise their kids. The victims, especially the young, sensitive ones, will be forever scarred by this tragedy.
Like the 9/11 attack. There were enough people on the plane to stop the terrorists, but maybe end up dying trying, and save a shitload of people. I mean if you're going to die, at least save a life right?
