Another thing to consider is why did the other guy get shot in the arm? Was he reaching also?
He would not have been standing next to the one killed if it happened as soon as he exited vehicle. Ricochet? Would have physical evidence of that in vehicle. Something to keep an eye out for in future releases.
“Traffic Stops” on a 40 mile stretch of barricaded highway ALWAYS have A couple dozen SWAT TEAM Sharpshooters on hand. Good thing Fido stayed in his kennel that night.
