A criminal trial expected to be closely watched by law enforcement and gun owners around South Carolina opens Monday in federal court in Columbia.

At issue: whether Joel Robinson, 32, is guilty of a crime for shooting a DEA agent in the first few seconds of a surprise federal law enforcement raid last October at his Orangeburg house.

Agents expected to find a cache of drugs, but a search of the premises found nothing but a small amount of marijuana for recreational use, according to legal records in the case.
