I must disagree that this was a set up.
Mainly, society in general is become desensitized by violence. What used to me lonely depressed suicidal maniacs who would kill themselves how now become a quest to take others with them and become famous. They do become instant celebrities, hated celebrities but not some lonely suicidal loner. They die with others, what they didn't have in life, they feel they get in death.
These are sick, deranged and evil people. And the more the media shows it, the more some psycho kid right now in America is looking at the TV thinking that they are going to do that next.
So, I do not believe this was set up by anti-gun people. My greatest reason, however, is because I loath the conspiracy theorists. The same ones who say 9/11 was an inside job, the ones who say Israel did 9/11 along with Bush. The ones who say the Zionists control all the TV stations. How Bin Laden died of cancer a long time ago, The conspiracy theories that I hate. When I look at people saying those conspiracy theories, I think about how stupid or brainwashed they are. Many of those jerks are the severely low IQ morons from Pakistan or other countries who come up with those ridiculous theories, but also in the US we have plenty of those "Dale Gribble" types.
I would not want to be like them but adding to more conspiracy theories.
What happened now is that a sick, deranged man saw the news of the Batman shooter, the Virginia Tech shootings, the Columbine shootings and he wanted to make a name for himself.
