Background:

“Charles Williams legally purchased a gun in Maryland.  He jumped through all the hoops.  He did everything right.  After picking it up from the shop, he dropped it off at his girlfriend’s house.  Later, he retrieved the gun and headed home.  He was arrested and sentenced to a year in jail for unlawful transportation of a firearm without a permit.”

Halbrook has argued before the Supreme Court three times, and each time he’s won.
