Haven’t we been here before?
Leftists never stop. If you are not a member of the NRA, you need to join now.
Note. SCOTUS has not decided on assault weapons.
SCOTUS could find against inherent legality of assault weapons as a derivative of _Heller_, which upheld a prohibitive tax on certain weapons “not suitable for militia use”. Don’t underestimate the potential damage by a case strangely convenient in content and timing during the “rule” of a President seemingly having strange persuasion on the Court.
IIRC, the NRA advocates keeping this type of case out of SCOTUS. Circuit Courts invariably uphold bans that are not total/absolute, and I would expect SCOTUS to, as well. In the past, when Circuit Courts upheld a partial ban, and SCOTUS was petitioned to hear the case, SCOTUS denied cert.
