I'm wondering where this is going to go. Various states and cities have been arguing that Heller doesn't apply to them because the 2nd Amendment only constrains the federal government. Apparently the lower courts have been split on that.
IMO this is very dangerous ground for the libs. If they win and the court finds that the 2nd Amendment only constrains the federal government, then it would seem to follow that none of the others would apply to states, either. Wouldn't that theoretically allow states to set their own voting ages, restrict speech or religion, deny due process, or even reinstitute slavery? That's an extreme example, but it cuts to the core of 220 years of Constitutional interpretation. There's an awful lot of law on the books that says our country believes the Bill of Rights applies to all levels of government. You can't cherry pick which ones apply based on your politics.
But if the court finds that the 2nd Amendment constrains states the way the other amendments do, then Heller becomes the law of the land and the entire gun control movement falls apart. I'm not a lawyer, but I'm having a hard time seeing an upside for liberals no matter how this turns out.
I think this might explain why more attacks are being launched against ammunition -- they're thinking the 2nd Amendment applies to weapons, not ammunition. Of course, that would set up a follow up legal battle over the idea of whether denying someone ammunition is denying them arms.
What does "gauge" mean anyway? As used here gauge means the number of round lead balls the same diameter as the inside of the barrel (aka the bore) that it would take to weigh one pound. It takes 12 lead balls the same diameter as a 12 gauge barrel to weigh a pound. The smaller 20 gauge would require 20 balls of that barrel diameter. The larger bore 12 gauge would require 12 lead balls of the bore diameter to weigh one pound.
In general the number of pellets in a shotgun shell...
