Think about this:

The only constitutional Amendment to ever be repealed was a ban. It was a ban on alcohol. How did that work out?

In 1932, wealthy industrialist John D. Rockefeller, Jr. stated in a letter:

"When Prohibition was introduced, I hoped that it would be widely supported by public opinion and the day would soon come when the evil effects of alcohol would be recognized.

I have slowly and reluctantly come to believe that this has not been the result.

Instead, drinking has generally increased; the speakeasy has replaced the saloon; a vast army of lawbreakers has appeared; many of our best citizens have openly ignored Prohibition; respect for the law has been greatly lessened; and crime has increased to a level never seen before." - Letter on Prohibition - see Daniel Okrent, Great Fortune: The Epic of Rockefeller Center, New York: Viking Press, 2003. (pp.246/7).

It's one thing to issue a ban to the Minions from 'Despicable Me,' like Australia did.

It's another thing to issue that same ban to the occupants of Mad Max's 'Thunder Dome.'

Not only is the US BUILT around the power of the citizen over the state, conceptually, from bottom to top, including the issuance of that right immediately after free speech and a free press; but people have been in possession of actual guns and upgrading their personal arsenals over all of that time.

If you think graft among mayors and police officers was rife over liquor, wait until you send a bunch of active military personnel out into the community to take guns off of people who they believe have every right to own them.

I can't imagine the day that you would get that kind of unanimous Congressional support and I pity the President who enacts it.

Let's not be 'pie in the sky' about this. Reality doesn't always follow what happens in the text books.
