How about when Richie says that he is pointing it at the kids?
The video starts at the pet isle, which the article says is 60 yards from where he picked up the airgun. Based on how he is swinging it around on the rest of the video he could certainly have pointed it at some kids before the video starts. We don't know what happened before the video, but from what we do know, the family is lying, not Richie.
