Sorry, that bit I quoted didn't include much opinion. Here's a better one. I think the position is rather clear.
From Nelson Lund, part of the Federalist Society's Civil Rights group:
"udge Cummings' opinion is much better reasoned than most Second Amendment decisions, and the Fifth Circuit is probably less hostile to the right to keep and bear arms than any other court of appeals. The federal courts have never struck down any statute under the Second Amendment, and the Supreme Court has not taken a Second Amendment case since 1939. Emerson could therefore lead either to a major advance or a major setback for the right that Justice Story called "the palladium of the liberties of a republic.""
And the link to go with it, LOL. http://www.fed-soc.org/Publications/practicegroupnewsletters/civilrights/second-civv3i1.htm
Anyway, you get the idea. :)
