Four words in the Constitution make all gun laws unconstitutional: “shall not be infringed.” The number of gun laws on the books at both the federal and state level is a measure of just how much tyranny we live under. It is also a measure of the cowardice of the US citizenry. The fact that we have this discussion over and over again shows just how far this nation has departed from what the Founders had in mind and how weak are “the people”.
Would you also say, "Five words in the Constitution make all speech laws unconstitutional: “Congress shall make no law"? Laws against libel and slander, the publication of national secrets, incitement, copyright, and obscenity are all unconstitutional?
Forget about prior restraint -- speech is restricted as to when, where, and the manner in which something is said in addition to the content. And leave out the second amendment. Are you saying that a law against say, libel, is unconstitutional because the first amendment reads, "Congress shall make NO law ..."?
