...It would seem shotgun 2 was on the right side of the truck when he tried to run by. Not visible....

Ah, NO! Youre wrong again. I know that eye witnesses often make mistakes remembering what theyve seen. Sometimes, people remember details in a way that fits a narrative they want to be true. Fortunately we have a video to help people develop a FACTUAL understanding of what they see.
Look at the image in post 75 up thread. You will see that the 2nd man was standing in the bed of the pickup truck. After seeing that still image, carefully watch the video again and confirm that the image came from that video and was taken a split second after the runner ran by the right side of the truck before he made his sharp left turn to attack the son.
So shotgun 2 was, in fact, visible. And was NOT, as you stated, Not visible.
I do not see a second shotgun anywhere. Do you?
Perhaps you are referring to a person?
