I agree with your beliefs that those in Congress who do nothing about stopping these massacres are mentally ill and so accept your desire to offer no solutions.  But why dismiss these suggestions without at least giving them a chance?  Push the mentally ill congressmen (most likely all Republicans) to enact them with a 3 yr sunset clause to test them out.  What's the harm in that?  Doing nothing does nothing.

As for the convicted felon, I must assume that if he served his time and thus declared rehabilitated, he should be treated like all other citizens and regain all rights.  If that means that he can get a weapon within 24 hours, then I'm all for it.  Isn't that how our system of justice works?
