On Saturday, CNN reported that a Chinese college student who made no threats, but had alarmed a roommate and a friend with his behavior and purchase of two semiautomatic rifles will be deported for an unrelated visa issue. University of Central Florida police said they were first alerted by a campus official in late January that Wenliang Sun was a "student of concern." Campus police received information that Sun owned an AR-15-style rifle and ammunition, but has recently been altering his appearance and his behavior was changing.
