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!
Clearly, this defendant has exhibited odd courtroom behavior. He also is representing himself, apparently. Based upon the papers he has filed and his other arguments and antics, not really enumerated in the article, the Judge senses that the Defendant may be incompetent to represent himself. (Thus, he appoints a Public Defendr and requests a medical examine for the protection of the Defendant.)
This is a smart Judge doing the right thing. He should not proceed if he has any cause for concern that the Defendant is mentelly incapacitated and cannot make decisions for himself. Defendant would be at the mercy of the state at that point. In addition, by having him cleared to represetn himself, he eliminates future grounds for appeal.
My guess is the man is competent, in the legal sense. He is probably just some anti-government wacko who has spent too much free time on anti-government webpages that trade in misinformation about the law and legal rights.
I would love to know the actual charges as well as the Other circumstances of his arrest. There are so many missing facts here. If he is on a hunger strike for 33 days, it seems he is not spending time just fo failing to produce his license. (If he is, he ought to fire himeself as his lawyer!)
