Face it if you bought a gun (long or short) after the Brady Bill was passed your name is in a database that will be used at some time in the near future to track down gun owners and their guns. Here in CA all gun purchase records are required to be turned over to the state when that business goes under, don’t imagine that even old sales (as in decades old) will not be entered into the “system” for use by your friendly LEO in taking away your guns.
Since the records had to be retained for three days, and since there is always the chance that a particular computer will crash over that three day period, most computers are backed-up on a regular basis.
This information exists somewhere and can be used for whatever purpose the feds or state law enforcement deem they can get away with.
I don't care.
I'm not paranoid about them ever showing up at my house. Let them bring a warrant for what they already know that I possess.
When the Feds come knocking on your door to confiscate your guns, the solution is to not be at home. Simple.
Good bloody luck searching every square meter of the state of Nevada for anything that I don't want found: Thanks to GPS, anything I hide and never recover is more likely to become part of the fossil record than to ever be discovered by chance. Ought to make for some interesting discoveries by Archaeologists some 500,000,000 years from now.
