Baloney. The government needs the power, they need a sufficient reason, and they need the support of the people.
"we are simply showing where it will end up."
Where it WILL end up? A little dramatic, are we?
California, Illinois, New York, New Jersey, and Washington DC all TOOK that power absent legitimate authority. They freely infringe RKBA to their hearts content despite Art 6 para 2, the 2nd Amendment, the 14th Amendment, and USC Title 18 Sect 241/242.
They do so using arguments JUST LIKE YOURS to pull an end run around protections for Individual Rights. This is why we label you "gun grabber", "troll", and many another well deserved pejoratives.
