The Muskogee County sheriff said a member of the group guarding an Oktaha gun shop accidentally shot himself Tuesday.
Sheriff Charles Pearson said the man dropped his gun and a bullet hit him in the arm. The sheriff did not identify the man or offer any other details about what happened.
The group of armed citizens and veterans is standing guard outside the Save Yourself Survival and Tactical Gear store after the owners said they received death threats from all over the world for putting up a sign saying Muslims weren't welcome.
"I saw several of those gentlemen out there yesterday," Pearson said. "The way they were holding their weapons, with the fingers on the triggers, you can tell a couple of these gentlemen have no idea about weapons safety. It's like the Clampetts have come to town," Sheriff Pearson told muskogeenow.com.
