If the SCOTUS rules favorably I expect to see a lot of proposed state and/or Federal legislation that requires tax stamps for handguns, .50 BMG, "assault weapons", high-capacity magazines etc.
Well, IMO it would depend on how "reasonable regulation" gets
hashed out, either by the supremes or otherwise. I doubt
anyone looking at constitutionality from a legal aspect would
consider existing federal gun law wallhacks (eg, the NFA system,
which is basically a ponzi scheme which disguises gun laws as a
"tax") to be "reasonable regulation" in the sense that said regulation
applies to other rights. EG, the common "exceptions" to
constitutional rights are supposed to be few and far between, not
numerous and expansive. While I realize that a lot of the other
amendments have been hashed out pretty heavily in courts, etc,
when you start looking at them most of them have not been
crippled so badly that the intent/spirit of the amendment is lost in
the process. If we applied that logic to the 2nd amendment, then
the majority the gun regs that are out there, would most certainly
not be considered "reasonable" by constitutional standards. EG,
for example, a law saying you can't fire guns into the air in a
city might pass muster as "reasonable" as such a law doesn't
really infringe on someone's constitutional rights, but a law which
explicitly bans a certain type of common firearm (like a handgun or
rifle) would most definitely be NOT "reasonable" .
