Don't know much about any of these. Looking at the first in the list found this:
https://casetext.com/case/us-v-lippman-3The court found:
The court rejects Lippman's constitutional claim on the ground that under circuit precedent, the Second Amendment protects the bearing of arms only when it is "reasonably related to the maintenance of a well regulated militia."
Colloton disagreed:
I would resolve Lippman's claim by assuming that the Second Amendment protects an individual's right to possess a firearm, and then examining whether the restriction imposed by § 922(g)(8) is a permissible regulation of that right. For the reasons stated by the court in its alternative holding, ante at 1043-44, and by the Fifth Circuit in United States v. Emerson, 270 F.3d 203, 260-64 (5th Cir. 2001), cert. denied, 536 U.S. 907, 122 S.Ct. 2362, 153 L.Ed.2d 184 (2002), I conclude that the prohibition on possession of a firearm by a person subject to a domestic violence restraining order is constitutional.
