The United States appeals the district court’s dismissal of the indictment
of Defendant-Appellee Dr. Timothy Joe Emerson (Emerson) for violating 18
U.S.C. ? 922(g)(8)(C)(ii). The district court held that section
922(g)(8)(C)(ii) was unconstitutional on its face under the Second
Amendment and as applied to Emerson under the Due Process Clause of the
Fifth Amendment. We reverse and remand.

The decision is very long, but so far the discussion of the 2nd Amendment
is very encouraging!
