The first people on the chopping block (no pun intended) would be the trans peopleNot long ago, I would have agreed with this. Now, I don't have any trust that a government organization can fairly perform this task.
next on the chopping block would be the autistic males (who have a very high percentage represented in these mass shootings). Anyone’s kids who are into military insignia, science/rocketry, d&d and miniatures, math, model railroads instantly suspect. Theater and English majors get a pass
next will be men with angry wives who file tros against them. You are in the system as being violent now. Up to you to prove you aren’t a real danger. Hope you have the money for a decent attorney
then they’ll go after you for political beliefs no doubt red going down first
