Because it has been completely ignored. All gun control laws are unconstitutional. The 2nd Amendment has alway applied to the states.
There is no right of the courts to “incorporate” rights.
I understand what you are saying. But this is in reality making the point that the states can not infringe upon the right.
Since the constitutional lawyers like Clinton say that the constitution is outdated, this piece of legislation brings the entire 2nd back right where it belongs.
Especially the part about people keeping to protect against a rigue government.
This in and of itself is massive for a gun control argument against what Obama is proposing with his bans.
What we are arguing now is purely what should be and then what happens in the real world.
What should happen, is that there should have been no need for this to be said. But in the real world of how things work, this went a long way to protect our rights to keep arms.
