Colorado gun-control laws ruled constitutional despite these arguments against them

U.S. District Judge Marcia Krieger has ruled that Colorado's controversial gun laws don't violate the constitution in a judgement Dave Kopel, who assembled a lawsuit endorsed by assorted businesses and dozens of Colorado sheriffs, has already pledged to appeal.

In May 2013, shortly after the suit was filed, Kopel detailed his arguments for Westword. Here's a look at why he believes the state's ban of all magazines that can hold more than fifteen rounds and a requirement for universal background checks on gun purchases are unconstitutional, as well as Krieger's reasons for deciding otherwise, supplemented by photos, two videos and three original documents, including the just-issued ruling.
