You can't get accurate stats on guns. Violates the 2nd.
In what way?
Unless guns are universally registered, it's just guessing.
Do you think universal registration violates the 2nd?
I have no opinion on that. You might have an opinion.
But the reason for lack of registration is the 2nd.
In any case, statistics on ownership are garbage.
Unless you interpret the "shall not be infringed" part as meaning
registration is unlawful, I don't see anything in the 2nd that would
otherwise prohibit registration. My opinion is they *should* be
registered.
