Plenty of Evidence
When my boyfriend was 14, he was living with his mom and sister on a housing estate. It was summer and he liked a bit of light in his upstairs bedroom, so he left the curtains open at all times. That included when he was getting dressed and after having a shower, 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 one bit. She went pounding on their door, yelling at my mother-in-law that her son was a disgrace, hanging around always naked and exposing himself to her daughter. My mother-in-law told her he had every right to do whatever he wanted in his bedroom, and that if they didn’t want to see him all they needed to do was not to look.
A couple of days went by and lo and behold, the authorities showed up at the neighbor’s door. Turned out the neighbor had been filming and taking pictures of my boyfriend to show to the housing people as evidence of his wrongdoing to get them kicked out. Except that the housing office called the authorities on her for taking pictures and videos of an underage kid and kicked her and her family out.
