Is This Guy Now a Prohibited Person?

Dave Hardy tells us of a pretty outrageous incident:

In the latest blow-back from the Virginia Tech shooting, State University of New York at Cobleskill suspended a student and sent him to a mental hospital for five days after he posted a photograph of himself posing with a shotgun on his Facebook page. According to reports, somebody found that image along with an away message that read, “I’m tired of people talking sh*t about my school.” As a result, last Friday Tharindu Meepegama (Thar), “a junior majoring in computer information systems, was escorted by the sheriff’s department to a psychiatric center in Oneonta, N.Y., where he was held until Wednesday.”

So is this guy now a prohibited person?   It seems he was involuntarily committed, but I’m wondering where the due process is?  To me, this is clearly an abuse of the mental health system.  If jurisdictions like New York and California want to consider an interest in shooting as a reason for psychiatric commitment, I may just reconsider whether I think there’s enough due process protections in the system to consider whether it’s sufficient to strip someone of their rights.
