Yongda Huang Harris, 28, was taken into custody at LAX on Oct. 5 after authorities noticed he was wearing a bullet-resistant vest and flame retardant pants under his trench coat. Officials say they found numerous weapons, including a smoke grenade, lead-filled leather-coated billyclubs, knives and a hatchet in his luggage.
Prosecutors say Harris' laptop computer contained violent movies showing young girls being tortured and raped.
Harris was a middle-school English teacher in Japan. His lawyer Steven Seiden said he was planning to learn the real estate business in Boston. While authorities do not believe Harris is linked to a terrorist organization, they haven't determined a motive.
A federal judge earlier denied bail for Harris, saying he was a flight risk and a danger to the community. He is due back in court Dec. 17 for a status conference. A trial date was set for Jan. 8.
