Special cars parked north on I-49 with a gun in the area of East MLK and South B Street. Our piece of icing just occurred, a white Cadillac with a license plate 78780 Adam Paul 643 and a white Subaru license plate 4 Paul Zebra Adam 402. Both vehicles were going east towards Polar Rock, flashing weapons at each other. All cars pretty close to 7-7, dispatch clear, 3-13.
