Yes they did, but breaking laws won't, for the most part, put supplies on dealer's shelves. If a gun is banned, it won't be on the shelf. Ditto ammunitioin. It won't be coming off the production lines either, except in a few cases. (Hopefully a few hundred, a few hundred thousand in the case of ammunition, black market manufacturers)
You sound like you're fairly certain that this about to happen. I know all about Obama's anti-2A stance, but you sound like you have some inside data.
So, where are you getting the information that this scenario is imminent, or are you just projecting your paranoia onto the rest of us?
