A group of people driving at least seven trucks bearing Confederate flags who taunted a black child's birthday party in July have been indicted via an “unusual legal maneuver” today that could give them added jail time.

The SPLC reports:

Witnesses told the SPLC that men got out of their trucks, brandished weapons and yelled racial slurs and threats. According to the witnesses, a few people yelled “f–k y'all ni**ers” and “shoot ‘em.” When someone from the party said, “There are kids here,” a person from the convoy yelled, “We'll shoot those bastards, too.”

…A Georgia state prosecutor today announced the indictments of 15 people who threatened African Americans and used racial slurs when they stopped at a family party while cruising around in a convoy of pickup trucks flying Confederate flags.

Ten men and five women were charged with issuing terroristic threats and participating in gang activity. Two of the men were also charged with battery for hitting a man at a gas station on the same day.

The SPLC launched an investigation immediately after the July 25 incident and turned over videos and other evidence to Douglasville District Attorney Brian K. Fortner. SPLC attorneys also brought witnesses to the prosecutor and have been representing some of the people at the party.

“Each of the 15 was indicted on one count of making terroristic threats, and a second count of unlawfully participating in ‘criminal gang activity,' the NYT reports.

The street gang laws carry a maximum 15 year sentence.
