What if these shootings aren't real? What if it is our government attempting to desensitize us? What if they are desensitizing us so that if they take control of us and begin shooting those who object to the control we won't be up in arms?
Like I said, totally worthy of a tin foil hat.
(Please understand that I am not trying to belittle what happened with conspiracy theories. I think every death at the hand of a nutjob is a tragedy. This was just a random thing that popped into my head when I mentioned the crazy conspiracy theories that people are going to come up with).
