Well sure but...that won't work in the circuits where holdings are against us, which is so far the 2nd/3rd/4th.
Look, what that means is the only remaining states where we can fight are Massachusetts in the 1st Circuit, the DC carry case (the one that multiple judges are refusing to rule on) in the DC Circuit and Peruta, if we get shot down en banc.
My hope now is that the Peruta ruling stands and takes effect, which means the Baker and Richards cases also stand because they're based on the same logic, and somebody on the losing .gov side petitions the Supremes.
We have, maybe, one last alternative...we drag the 11th Circuit into it. There are no may-issue states there BUT both GA and AL have laws banning the carry of guns at political rallies or protests (even legal ones), which violates the hell out of the 2nd Amendment and we could in theory get a pro-carry ruling that way.
OR we do a suit against one of the federal no-guns-in-our-building bans? Won't work against a courthouse, but against a toilet in a national forest? Just thinking out loud here...
