However, when the SCOTUS ruled on June 26, 2008, that the Second Amendment is an individual right they allowed that, like the First Amendment does not permit shouting “fire” in a crowded theater, the Second Amendment does not allow “everyone any gun.” Government has the right to “reasonable regulation” of the exercise of the right. What they left to be determined is what “reasonable regulation” does or does not include. They did say an outright total ban on handguns is a violation of the Second Amendment.
The net effect of these technologies is to try to ensure the Government can out-gun the civilian subjects, . . . er . . ., citizens. Oh, and confiscate those owned by lawful citizens at will.
But criminals will still have the unregistered, fully-automatic AK-47s and Uzis with 30-round magazines. They will probably also have the phased-plasma rifles in the 40 watt range once they are a reality.
