I think there is ample evidence on his own web site and in his behavior that the mental health card is not just a bluff!
I don't think the mental health card is a bluff at all. It is a tactic used by courts all the time. As mentioned by others on this thread, it is a tactic employed by dictators and tyrants throughout history too.
If the judge is bluffing, it sounds like it will fail because this guy seems pretty determined to make his point. If the judge is serious about the mental health issue, then we need to determine what sort of threat this guy really presents to society.
I think this guy is protesting against the excessive use of force and control in the society, and the judge's action just proves his point. The judge should just make the appropriate rulings, find the defendant guilty, impose a sentence, and then let the defendant go, just like would happen to anyone else committed these misdemeanor crimes. If the defendant then continues to act out on his beliefs, then you deal with such offenses when they occur. If the defendant escalates his anarchism to the level of presenting a danger to society (like he threatens or assaults someone with a gun or something) then maybe the mental health card would be a more appropriate course of action for the judge to take.
I have a problem with the government wasting resources on a malcontent like this guy who does not appear to be a threat to anyone when rapists and other pathological criminals are freed all the time by the courts.
