Did you read my point #2? I would bet any amount of money that I was the only person so dressed within a mile radius. It was a false report and one of my questions to the Chief and what follow up is done with “concerned citizens” such as my accuser.
Either the woman who called in the complaint made a mistake, was actively trying to cause you a problem, or there actually was someone your size, gender, approximate age and coloration wearing similar clothes, looking into her car.
The officer was just doing his job. Was he courteous, professional? Were you free to go on your way promptly, after the exchange? Did he follow you or something, afterwards? I’m not sure why the upset.
