Court deciding on reach of federal gun ban – The Supreme Court debated Wednesday how to apply a federal gun ban to those with misdemeanor domestic violence records, with justices trying to figure out a middle road between what one justice called two extreme positions.  Justices heard arguments from government officials who want the ban to apply to James Castleman, who pleaded guilty to misdemeanor domestic assault in 2001 in Tennessee. He was then charged in 2009 with illegal possession of a firearm after he and his wife were accused of buying guns and selling them on the black market.
