Nevada is one of the few states in the West to have restrictions on closing gun stores in emergencies. In Illinois (of all places), gun stores are listed as essential. In California, not at all. Gun stores across the state are being closed by public health authorities as "non-essential" businesses. A few are being allowed to finalize purchase/pickups from people who were in the middle of the waiting period.
California is likely to find itself in the cross hairs of a lawsuit over this issue. Hopefully the government's over-reach in shutting down gun stores in the face of what quite possibly may be future civil unrest will be crushed. Or courts may just rule that the government can abuse the constitution because things are really, really bad because government failed in the first instance.
The Pennsylvania Supreme Court dismissed such a lawsuit without comment. What we are seeing is that some states are creating an indefinite inability for citizens to buy firearms and ammo. The full force of the state, along with the approbation of much of the uninformed public, can be used to grind these stores into dust.
