The mental health angle is going to nab a lot of gun owners before open hostilities commence. I've had a few people tell me local cops use the "are you okay?" line to bait you into 'admitting' you're not, and therefore fitting within the legal flytrap of being mentally off. Then they feel they can sidestep your rights and take you and your guns. They also want more reporting from medical personnel about if you own guns and if you admit to not being absolutely chipper and nothing's wrong.

The rest of it is tightening up on the current system until they can pass new legal bullshit.
