Just think of some of the images portrayed by the media in the past two decades. I instantly recall the-- I believe it was the Stockton schoolyard massacre in 1989-- remember how the news showed endless images of the AK-47 and bayonet with the chalk drawn around it?
Someone correct me if i'm wrong, but there hasn't been a great deal of deaths by bayonet in the past century... but a ban on rifles with a bayonet lug was included in the Clinton AWB, I presume, is because feelers had been exposed to that very image, and it looked so downright menacing... scary.
That's the power of mass media, if they can condition even gun enthusiasts to develop an adverse reaction to the image of their choice. Expect a whole lot more of it, because I believe that many feel the time to strike is now when emotions are running high. And, at the risk of repeating myself, emotion is what they have most on their side right now. They are all for banning things that "look scary".
