But that's not 2 billion dollars per year; that's 2 billion dollars that have already been spent. Axing the program afterwards guarantees that the 2 billion dollars is a waste of money. Furthermore, police chiefs all over the country have said that the registry was useful; they would consult it every time they had to respond to a call at a residence, especially for domestic violence. They wanted to know if there was a firearm on the premises. I totally agree with you that a person who purchases a gun in order to use it illegally won't register it, but that doesn't mean that a person who buys a gun for protection and registers it won't someday use that gun in some violent way. While I'm not generally a proponent of government tracking the citizenry's posessions, I can easily make an exception for lethal weapons.
