1. Unlikely that the House of Representatives would pass a new gun law or renew the "assault weapon ban" because it would be political suicide -- but it might happen now, or in two years with new House members.
1a. IF such a law was passed, it would go to the Supreme Court and be found unconstitutional.
2. The UN treaty on gun control would be unlikely to pass the Senate with a 2/3 majority because it would be political suicide -- but it MIGHT pass now, or in two years with new Senators.
2a. IF such a treaty was passed, it would go to the Supreme Court and be found unconstitutional.
3. The President could issue an Executive Order during a "state of emergency".
3a. IF such an Executive Order was issued, it would go to the Supreme Court and be found unconstitutional. (Not in time to prevent confiscation, but eventually)
4. Unfortunately, the Chief Justice of the Supreme Court recently issued his opinion: anything that the President wants to be "constitutional", IS "constitutional", even a Federal Law saying that the government can make you buy products from private businesses -- like health insurance companies.
This Forum is about self reliance. The government of the United States is "we the people". "We the people" declared gun confiscation to be illegal on April 19, 1775. That decision still stands, only because that same "jury" still has the final say in the matter -- unless we give it up by our own action/inaction.
Keep you guns somewhere safe. Continue to prepare for good times and bad times, both will come eventually.
