Marine amputee actuitted on gun charge

From the Center of Insanity our nation's capital:

After being deadlocked twice, a D.C. Superior Court jury yesterday acquitted a Marine amputee on felony charges of gun possession stemming from an arrest while he was on the way to Walter Reed Army Medical Center.

In the 2006 incident, Cpl. Melroy H. Cort, 24, and his wife, Samantha, were en route from their home in Columbus, Ohio, to Walter Reed. Cort's legs had been amputated above the knees when he was wounded by a makeshift bomb in Ramadi during his third tour of duty in Iraq.
...
Cort, who said he had a permit to carry the gun in Ohio, said he had it with him because he had moved out of his house in anticipation of an extended stay at Walter Reed.

He said his commanding officer had advised him to take the gun to the armory on Walter Reed's base as soon as he arrived.
...
Although acquitting him of the gun charges, the jury found Cort guilty of possessing ammunition, a misdemeanor. He was sentenced to time already spent in the D.C. jail.
