The rifle was a Smith & Wesson AR-15 pattern rifle. But this guy moved to California (where neither rifle nor magazines are legal for sale) from New Jersey (ditto) two years ago. He is way too young to have acquired these before the respective state laws took effect.
The note found in the duffel bag suggested Ciancia was willing to kill almost any TSA officer."Black, white, yellow, brown, I don't discriminate," the note read, according to a paraphrase by a law enforcement official briefed on the investigation. The official spoke on the condition of anonymity because he was not authorized to speak publicly.The screed also mentioned "fiat currency" and "NWO," possible references to the New World Order, a conspiracy theory that foresees a totalitarian one-world government.When searched, the suspect had five 30-round magazines, and his bag contained hundreds more rounds in boxes, the law-enforcement official said.
This November 2, 2013 USA Today article says that the shooter bought the rifle from a Los Angeles area gun dealer. Huh? How?
