Dwan Thigpen, 34, was arrested and charged with intent to murder. The other guard was not injured. Two civilians also avoided injury by ducking.
The incident occurred during an argument between the two officers. A third officer attempted to break up the argument, trying to keep Thigpen from using his gun.
All three guards work for Vance Federal Security Services.
