"given he “knew” he wasn’t breaking any laws"
I may know that I haven't broken any laws, but that doesn't mean someone didn't call 911 saying they just saw someone who matches my description, in a car like mine, robbing a bank a few blocks away.
(speaking of prior events ... there was one several years ago in ??Tennessee??. The family was on vacation. Dad left his wallet on the car roof at a gas station and money is blowing in the wind. Someone called 911, and as the family blissfully rolls down the interstate the call gets handed off from one jurisdiction to another. It's like kids playing 'telephone'. Eventually the dispatchers are telling officers it is a kidnapping, IIRC, and the bewildered family gets the full felony stop experience. That was a sucky situation, but it sure wouldn't have helped if Dad started arguing.)
