This is not an uncommon way of getting around the right to "free association"
While it is my stance that guns should not be handed out to the average citizen, I don't like the precedent this sets. What if someone then sues to see the membership of something like a LBGT group. There was a law in the 1950s or 1960s that was struck down as unconstitutional to force "terrorist groups" such as the AFL-CIO to turn over membership records.

However, the government still should have this data, if only because it helps with crime fighting.
