She said she puller over because he was riding her bumper.
He wasn't, but it DOES look like she pulled over to let him go by.
For that matter, he pulled her over for changing lanes without signaling, for which he a) stopped her for almost 6 minutes and ran her record and b) had no intention of giving her an actual ticket and was just going to let her off with a warning anyway. IOW, he was pretty much just being an authoritarian bag of dicks.
He rolled up on Sandra in the middle of a power trip. Sandra told him where he could shove his power,
and he snapped.
Does anyone here honestly believe that even a person suffering depression would go from "combative and belligerent" to "suicidal" after just three days in lockup? I personally don't. Not unless something happened during those three days that pushed her over the edge. That, of course, is assuming the police' version of the story is reliable, and if the dashcam is any indication, it ISN'T.
