If you want to have an effect on a problem, you need to have reason to believe your action will be effective. Next, it has to have enough popularity to be made into law AND pass SCOTUS scrutiny. So, back to my question, have you got ANY evidence that 90 days is the best answer?

As for taking all the guns. Sorry if you actually believe that is my position. It's not, quite the opposite. I hold that is the position of most liberals and that any gun law passed will only be a stepping stone to their ultimate goal.

For that reason, if you want to get a law passed you will need to show that it will be effective at reducing gun violence (not stopping one shooter) and at the same time have the minimal damage to A2. 

SO no! you cant just try this, then that then another thing. Because when you do, you enact 3 laws that wont effect gun violence but inhibit legal gun ownership.
