Don't you just love Texas.
My understanding the gun dealer keeps all the records, but they are not sent or put in any database. If your gun is never used in a crime and recovered, there is no reason for the information on the forms to be ever looked at by anyone. I suspect if in the future, a government could require that all that old information be sent somewhere and put in a database. But the political climate would have to be a lot different than it is now.
My favorite line from the movie "Red Dawn" is when the Communist Col. asks his men to search the gun records to find the gun owners in town. I think they end up executing the owner of the gun store because he does not have records on the hunting rifles he gives the kids, when they come in for supplies.
Some people do not believe in CHL because this tells the government you have a gun in your possession.
Thus if you are worried about these things, you dont have a CHL and all your guns are direct cash person to person sales. And I guess the person you buy from shouldn't know you either, as your friend could crack under torture to give up your name.
