Since there is no such thing as a national registration (Firearm Owners Protection Act of 1986) we're OK on a national level. The Feds don't have a clue as to what we own. On a state level, well, those poor fools who live in a state that has a state registration might have some problems. The bottom line - for me - is that I have no guns ever since that horrible boating accident years ago.
Life is tough. It's tougher if you're stupid.
