No, the police report indicates and Chief Jackson said that Officer Wilson left the sick call at 12:00:00. He did not leave it at 11:54. That is incorrect.
I understand exactly what the police reports state.
However, given the two addressees that were provided, googlemaps indicates that it takes approximately 10-11 minutes to traverse this route.
To arrive at the scene of the shooting at the time stated, he has to leave much earlier than dispatch has him leaving the other scene.
