Line 11 has the and. Looks like mandatory registration of all guns to me. Glad I live in Arizona...
Except that apparently, if you UNLAWFULLY owned a gun prior to the enactment of this law, you are not required to register it.
Only if you take possession after the law is passed, OR you LAWFULLY owned it prior to the law being passed.
The semi-colom before the (2) would seem to mean that the and doesn’t apply to the (1).
