Isn't there something in the Penumbra of the Constitution that protects privacy? The "access to more data about guns and their owners" sounds like a direct violation of that absolute right, not to mention the flagrant infringement of another right that "shall not be infringed".
something about being secure in your persons and property...
pesky thing...4th Amendment?
The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized
“secure in their persons” gee...wonder what they met by that?
