We should indeed be scared, the anti gunners will stop at nothing, and they have not been doing so well lately, and honestly I am surprised it took this long, but it is not the first attempt,IIRC. If it fails it certainly will not be the last. As things become more "green" expect the antis to use this strategy more and more, and don't be surprised if it is something tacked on a bill at the last minute, especially something that would benefit gunners. For the youngsters around there was the firearms owners protection act, 1986, yup, under Regan, allowed all sorts of things forbidden by the 1968 law, like buying ammo and components through the mail, importation of surplus military arms, the youngsters do not know what it was like. As nice as that law was, during an act of last minute poltroonery and subterfuge further machine gun production for civilians was banned. This meant only the rich will be able to afford machine guns, especially as time goes by.
It will be much easier to convince the public to ban lead than to ban guns, they hopefully would never go for that, but ban lead, didn't they take that out of gasoline and paint? Gosh, without lead, babies will be safe the world over...... So, outfits like Barnes and others(notice how many lead free bullets are now being made by companies that never used to..) would get rich, and shooting would become a rich mans game. With lead banned, they would go after hand loaders, who are sick enough to have to make their own ammunition(I heard Feinstein or Metzembaum or Kerry, Kennedy- one of those creeps actually said this) and would easily circumvent the law-banned. In some countries reloading by an individual used to carry the death penalty, but this was a while ago, now I don't know(think it might have been during the '70s when Rhodesia was falling apart, the Continent was/is in turmoil).
I hope it does not happen, but it could be an administrative thing that gets us, then Congress will have to overcome it's considerable inertia to do something, how likely is that to come about quickly. Sigh...
