If you catch a guy who shoots dead a TSA agent and is captured carrying a leaflet in favor of a worldwide Islamic Empire, let me know, okay? unfortunately, the recent killing at LAX was not a Jihadist terror attack.
Nope. mr. Ciancia, age 23, was caught carrying a leaflet from the Patriot fringe movement, a group which harbors paranoid conspiracy theories regarding a "New World Order" that they fear will replace he US government with planetary socialism.
It is possible that Mr. ciancia might be mentally ill. But at this moment there is really no evidence in favor of that notion. It looks far more likely that either he was recruited by thee "Patriot" group, or he was a lone wolf who was influenced by their propaganda to commit a murder of a random TSA agent.
