The body-cam footage from the 2nd officer, the officer approaches the van and says to BL, "Hey, we got a call about a male hitting a female and the two of them getting in this vehicle and taking off." Gabby is already out of the van at this point.
BL responds, "Sorry, I, I, I, I, don't have time to defend myself by sitting here."
This exchange takes place at about 30 seconds into the footage.
That, along with him being less jovial with this officer, has always bothered me. He doesn't have time to defend himself? Or, he has time to defend himself but not while sitting? Either way, it reads to me, that he believed hitting Gabby was a defensible action on his part. Sorry, it's not.
Given his "... I don't have time..." response, it's no surprise to me that he's "missing". If even just from a moral standpoint, he needs to own up to his actions.
