Gun show fail.

You'd think before discussing an issue, you'd at least make a small effort to not be completely wrong about the issue. Apparently, that's asking too much of Brady Campaign member Joan Peterson:

So if loaded guns are prohibited at gun shows, they should be prohibited in other public places as well. If law abiding gun owners are willing to leave their loaded guns at home when going to shop for more guns, surely they can leave them at home when they go to the shopping malls or out to eat.

That's simply not true. There is a blanket prohibition that applies to guns that are being displayed, sold, or handled by the public. But by law, gun shows are no different than gun stores, shopping malls, restaurants, or any other retail establishment. You can carry a loaded gun as long as you are in compliance with the law and the property owner's rules.
