fwiw she didn't have to answer any questions, he would have had to work a lot harder to establish fake probable cause if she hadn't talked...

So I wonder if we could be seeing a bit of survivorship bias.

¹though with cops you never know

In this case, the Flock data then showed a bunch of recent interstate travel, which cops consider to be probable cause. They know it’s not legally probable cause though, so they pointed to her “nervousness” (aka not consenting to search).

The real question is how many times the same cop pulled over people who he searched and found nothing. Certainly nonzero.
