Limiting access to gunpowder is already being proposed.

No, I'm not seeing black helicopters flying around, but there are just too many things that just don't add up. I DO NOT trust the American media any more; they are nothing but media spokespeople for Obama (what I and others are calling co-conspirators). This is the PERFECT setup for more anti-gun legislation. The latest that I heard was that the bombs were made out of gunpowder, and that a Senator (Luger, maybe?) asked "How does just anybody go into a store and buy gunpowder?"
Get ready; "We need to regulate gunpowder. If somebody wants to buy gunpowder they will need to register and wait for their name to be cleared". If they can't grab our guns, they will make them useless.
