Do you have a copy? I'm looking at mine now. Specifically at the disclaimers for its use in forensic settings (pages xxxii-xxxiii). I wonder if the feds will push the APA to strike these disclaimers from version V when it comes out in a few months.
The disclaimers can be disregarded. All the government needs to do is to issue a directive that anyone known or suspected of suffering from a mental disorder as defined by the DSM-V is prohibited from owning or possessing a firearm.
That would include everyone.
