National level - Yes.
-It should be federally mandated that all 50 states to participate in the requirement that ALL felons be registered into a database, and their records appear on background checks.
This would have prevented the Texas church shooter from buying a gun.
-Removal of the Promise Program. Police should arrest criminals, and not be federally compensated for not doing so to keep arrest numbers down.
This would have prevented Cruz from buying a gun.
-Remove the 'Gun Free Zone' label. Whatever school personelle who are trained in the use of firearms should have the ability to defend their students and themselves.
This would remove the perception that public schools are shooting galleries with zero resistance until the police show up and not cower outside.
State level - Yes.
-Get rid of stupid and ineffective gun laws that makes it impossible or very inconvenient to acquire and carry a gun, which criminals seem to be immune to, for some reason.
There's my proposals, Rational, to fix the problem of school shootings and high murder rates.
