You would never know by the emotional charge of the video that pepper spray and tear gas grenades are non-lethal! I was waiting for a 31 round magazine to be protruding from the weapons table for further emotional drama.
I could see him being commited to a psychiatric hospital, based on the heightened and somewhat misguided fears people currently have, but don't see where he broke the law. However, he probably does not have to break the law to lose all his weapons if he gets hospitalized. Not knowing Massachusetts law, my closest guess to a law violation might be an super loose interpretation of reckless use of a weapon and a super vague terroristic threats charge. But then again, there is a chance that his spouse was misinterpreting things. When I worked in mental health crisis in suburban Philadelphia, it was practically a guaranteed commitment approval by the county if there was mention of a gun in the documentation.
Speaking of a lack of "guts," could this be another situation where everyone involved willingly looked the other way for the past 9 months? If people are that scared of the amount of items he had, would they not have been just as scared with half that amount 4 months ago? There's a piece of the story missing here. Based solely on what was said, I would have a real hard time letting the guy go without care too. Maybe this is the full story, or maybe it is just a misinterpretation based on misguided fears. I would be curious to know if there is further information on this guy and what happens to him.
If I had money, I would bet that this will be another case where the media will overlook the individual's mental health and go right for the second amendment's jugular.
