To top it all off, how is it “common sense” to establish a gun registration system in America that would apply only to law-abiding citizens, not criminals? That question has been starkly answered by the U.S. Supreme Court.
In 1968, the Court reached a landmark decision in the case of Haynes v. United States. Miles Edward Haynes decided to fight his arrest for possession of an unregistered, barrel-shortened shotgun. His argument was brief. Because registering the firearm would force Haynes to admit to having unlawfully possessed the shotgun before it was registered, Haynes argued that registration laws violated his Fifth Amendment protection against self-incrimination. The Supreme Court agreed, and in an 8-1 decision ruled that individuals with a legitimate claim of self-incrimination are immune from registering their illegally possessed firearms with the government.
The upshot of this case is that registration requirements can only be enforced against the law-abiding, the same people who own firearms to protect themselves against violent criminals.
