Plenty of Evidence
When my boyfriend was 14, he was living on a housing estate. It was summer and he liked a bit of light in his bedroom, so he left the curtains open at all times. That included when he was getting dressed, so if you purposefully stared at his window, you could see him from his waist up (and only his waist up).
Well, their neighbor did not like that. She yelled at my mother-in-law that her son was a disgrace, hanging out always naked and exposing himself to her daughter. My mother-in-law told her he had every right to do what he wanted, and that if they didn’t want to see him all they needed to do was not to look.
The authorities showed up at the neighbor’s door. Turned out the neighbor had filmed my boyfriend to show the housing people evidence of his wrongdoing to get them kicked out. Except that the housing office called the authorities on her for taking videos of an underage kid and kicked her out. _darksoul89
