Loopholes galore in that section. The person is required to “document” his sanity after confiscation . Only the wealthy will be able afford self defense soon.
No, they just have to show they have been released from custody and is no longer subject to involuntary commitment. That is not the same thing as having to document sanity. In fact that section does not address the competency of the person. (Which is pretty much assumed because they were released.) It addresses the time limit put on returning the seized weapons which is 24 hours after the person can provide documentation that they were released and not subject to involuntary commitment. You’d think their presence would make that obvious but government lubs them some paperwork.
