Frankly, the opinion of anyone who thinks the word "confiscation" has a v in it doesn't really matter that much to me. People are acting like that would be a whole new type of government activity. If the government forces people to sell them their assault weapons it's virtually the same as exercising the right of Eminent Domain on real estate. There's mountains of precedent for that. This thing is needed for government purposes, you can't have it anymore, but we will compensate you handsomely for it. Been there, done that.
