By putting this issue under the federal umbrella, do you think further increasing of rights is likely, or less likely?
The Constitutions of the Several States applies to RTKBA..for that state, as the DC v Heller case showed, States may impose reasonable limits on the State, but cannot outright deny the RTKBA.
By expanding the scope of the FedGov one is merely opening the door to yet more restrictions, though I doubt one realizes it.
I think it's a clusterf*ck of epic proportions cobbled together to try and redress other even f*ckier clusters perpetrated by previous legislators and court Justices.
All we need is for RKBA to once again be regarded as "the Supreme Law of the Land, the laws of any State to the contrary notwithstanding and the Judges in every State shall be bound thereby" and stupid stunt legislation like this one wouldn't need to be attempted.
As long as this legislation sticks to making Carry licenses akin to marriage/driving licenses... It won't do additional harm. I ain't holding my breathe that the current crop of GOP-ers can get that clean a bill past Dingy Harry's Senate or Zero's veto pen.
