Actually John.. From the video I saw.One of them ran at high speed straight towards the Police car yielding a meat cleaver.. In my estimation he was shot roughly 5/6 foot from the vehicle just as the copper opened the vehicle door..
His scum mate seemed to have bottled it and followed the foot path which is where he looked to be shot down..
Cant be 100% sure as there was a large tree blocking the view of the elevated camera.
