THIS IS WHY WE MUST UNDERSTAND THE CONSTITUTION!
The executive branch HAS NO AUTHORITY IN THIS AREA! It can sign executive orders until the pens fall apart - and IF we understand the Constitution, NONE OF IT will have ANY effect! We would simply laugh at the tyrant wannabe who thinks the pen is mightier than the Constitution.
I also heard on the radio yesterday someone from the NRA bemoaning the danger of the UN small arms treaty. The same principle is at work here! The second amendment SPECIFICALLY PROHIBITS the federal government from having any say in the firearms owned by citizens -- and Article VI clearly states that only treaties made in areas where the Constitution grants authority to the federal government, and in NO OTHER AREAS, are considered law! They can yak all they want -- if we know the Constitution it is a usurpation of powers not granted, therefore NULL and VOID - of no effect or substance!
