Had a friend over earlier who had a copy of the video. I noticed something very strange.
He reaches a particular point on the road and stops for a full minute, turns off the audio for a brief moment. He is waiting for a signal...then at the 4:04 minute mark he signals a person on the side walk (bright red coat).
Once that person passes, he turns on the light on his gun and proceeds to go to the mosque.

Notice he waits for the person to pass the car before switching on the light and driving on.
A person is seen coming on the sidewalk
