David Smith of Los Angeles was sentenced Friday. He was convicted in April of making criminal threats.
The 40-year-old is a former student of Soka University in Aliso Viejo.
Prosecutors say last fall, Smith sent threatening messages to a university spokesman, saying he had “nothing to lose” and would “make some examples that no one will forget.”
Sheriff’s officials say Smith then sent a link to a YouTube video showing Smith in a bathtub with a semi-automatic pistol on his chest.
Authorities say Smith possessed nine loaded guns when he was arrested last year.
