I just watched the bodycam footage from this, and to my surprise these cops were very well behaved. They never cuffed the guy, or in any way escalated the situation. They figured out very quickly it was a mistake and let him on his way.
Well, of course. It was a white couple driving an expensive car.
But, on the other hand, they failed to check that the license plate matched the plate they were looking for. The stolen plate was reported as either "34 DTM" or "34 03 DTM" (the article isn't too clear on this point: the report to Flock was "34 DTM", but it's not clear if the original police report was for that plate or "34 03 DTM"). In any case, these plates did not match the plates of the car that the author was driving.
One would think that checking the plate would be the first thing the police would do before apprehending someone, but apparently not.
So, well behaved, but incompetent. I am not sure that such incompetence qualifies as well-behaved.
