I think you are oversimplifying Red Flag Laws. I would characterize myself as pro-2A, and while I don’t speak for anyone but myself, I think most rational folks like myself don’t necessarily have an issue with Red Flag Laws, in fact would characterize myself as pro RFL. Don’t misunderstand opposition in implementation with opposition to the methods which are employed.
For me, there has to be a hard time limit where the accused, with counsel, may confront the accusations.
Indiana has a decent law, that continues to be tweaked. But it still didn’t stop the Fed/Ex shooter, because the Marion County Prosecutor failed to do his due diligence. But sure, what we clearly need are more laws.
