The phrase “got your six” is a variation of “got your back,” referring to the method of using a clock face to denote direction. So, your 12-o-clock is directly ahead, your 3 and 9 are your right and left, and your 6 is behind you. Kind of a weird thing to put on your license plate, but I’ve seen weirder.
Yeah, there’s always the underlying faith in the system in these types of stories. They assume that if someone was found guilty, they must have done it. The only ones that I see that go against that are ones where’s it’s been proven that they were falsely convicted, and even in those it’s usually framed as some freak one-in-a-million accident without anyone at fault.
