Or use a silencer (actually I know that all they do is suppress the noise, but I will use the colloquial term rather than the technically correct suppressor). Not real clear to me why more folks don't like the idea of reducing gun noise. The ATFE and the rest of the gun grabbers get their knickers in a twist, but more widespread use of suppressors would help IMHO.
In 1934 a bill was passed levying a tax of $200 (4 times the price of a Thompson submachine gun at the time.) on future sales of machine guns. Short-barreled rifles and shotguns, cane guns and silencers were also thrown into the bill, almost as an afterthought. The BATF was set up, and one of its functions today is to collect such a tax. So much of the controversy dealing with Title II weapons is not that they are illegal, but that a tax will be levied on their ownership. Owning one which is not properly registered and taxed is a violation of federal tax code (tax evasion) a felony punishable by large fines and up to ten years in prison.
