With the addition of the 5th Circuit case, NRA v. BATF, to those that have filed for petitions of certiorari, that now gives us 4 cases (and a 5th, should the New Jersey case be added).
The cases seeking a grant of cert are:
Woollard v. Sheridan
Lane v. Holder
Schrader v. Holder
NRA v. BATF
The state of 2A law is in complete disarray. The Court, desperately needs to provide some form of guidance to the lower courts. Else Heller and McDonald are meaningless.
