We already have background checks..no need for anything else. Dems dont want to talk about mental health since the majority of the mass shooters are commies
With universal background checks will come penalties for breaking the law, and the only way they will know if you sell your pre-UBC guns is if they have universal registration.
Liberals don’t want Mental Illness considered as it will lead to stigmatization of the poor souls suffering from the same affliction that constantly afflicts Liberals!!!
