do not know the answer to your question nor the local details.
Perhaps others in state or in the profession
See my post #116...gives the statement discrepancies and the links to those statements...its pretty simple, a dash-cam in a police cruiser is pointed to the front of the cruiser but in this case the incident occured behind the cruiser after the cruiser got in front of Kenney fleeing to stop him by blocking.
I wish that I could explain the details of this, but I would be guessing.
