Gun rights have always been selectively applied, tax or no tax. There have in the past been laws (to attempt) to prevent certain groups of people from buying firearms by restricting the availability of the only firearms they could afford, namely inexpensive (or cheap, if you will) guns. We used to call them Saturday Night Specials, among other things. I can't name any such law but there was a belief that such guns were invariably the guns that criminals used. It was believed that criminals did not used quality guns like Colts.
Shoot low, sheriff. They're riding Shetlands!
Underneath the starry flag, civilize 'em with a Krag,
and return us to our own beloved homes!
Buy War Bonds.
