This is scary, Aurora PD reports that the shooter identified himself as "the Joker" upon arrest. I fear we may not see an answer to the question why. If anyone knows much about the Dark Knight comics, the new Joker is the representation of chaos, there is no reason but to disrupt the status quo and create more chaos. Rewatch The Dark Knight and focus on Ledger's Joker, it might give some insight into the motives behind this sick fvck.
I think the shooting community needs to step up and stress to those not in the know that these "active shooters" that pull this depraved, heinous and horrible crap are a very small number of gun owners, like fraction of a percent. It's terrible that it takes a tragedy like this to bring us together, but like with Columbine, and 9/11 and other terrible events, it shows that we as Americans rise up and come together as one, and I think that is the one good thing that can come out of these horrible horrible acts. They need to try this guy as a terrorist.
