Well damn. SCOTUS denied cert to all those gun cases.
Justices Kavanaugh and Thomas dissented to the denial for Rogers v. Grewal and as usual Justice Thomas' dissent is brilliant. He obviously laments the fact that liberal lower courts are intent on nibbling at the edges of the Heller decision (to the detriment of the 2nd Amendment) and is champing at the bit for a case that will enable the court to stamp "HANDS OFF OUR FUCKING GUNS!" on it.
EDIT:
BTW, this doesn't necessarily mean there was no merit in those cases and they individually are lost causes, it might be that the way it presented simply didn't give compelling enough a reason for SCOTUS to give it its attention.
