How do you address this problem with out background checks.
A straight answer please, no bull ****.
Background checks are for unConstitutional discrimination qua a fundamental Constitutional Right.
The USSC has held that government cannot discriminate
in regard to even a few moments of poorer seating on a bus.
Everyone has a Constitutional Right to EQUAL PROTECTION of the LAW
including the equal right to defend his or her life
from the violence of man or beast (e.g., dogs in the streets).
That 's how it was for a long time, before gun control.
