You have to wonder if this person approves of government keeping lists of those who check out certain books from the library, or buy them for that matter.
Besides the obvious problems with "shall not be infringed", guns used in crimes are very rarely used by the last traceable owner. They are either stolen, or bought in back alley somewhere, usually after being stolen, but sometimes acquired more or less legitimately, but without a paper trail. The only real reason for such lists, are to make confiscation easier "when the time comes".
The government does, you know. Patriot act. BTW, it is illegal for librarians to tell anyone about it, so don't expect a lot af attention directed to this policy.
