You may have heard the story today of a guy in one of the dorms at the University of Central Florida who shot himself and had hundreds of rounds of ammunition and explosives. It turns out he was planning a mass shooting
, according to police investigators. He set off an alarm hoping to set up a turkey shoot as panicked students evacuated the building. But police seem to have arrived on the scene so quickly that "his timeline got off," in the words of the university police chief, and he turned the gun on himself.
