Your man was trolling central park and throwing out doggie treats to rile up dog owners. He is an idiot looking for twitter fame, and he got it. He ruined this woman’s life by uploading video. Ask yourself why he and his sister uploaded the video?
Who made this black man the dog enforcer of Central Park?
Back in ‘your day’, when DINOSAURS RULED THE EARTH (/plummy announcer voice) there was an very popular TV show called Candid Camera. In part, it did much the same thing. It also resulted in millions of people laughing at the setup’s unwilling victim and no few times amounted to career suicide for said victim when they behaved badly. How is this any different for an end result?
She was breaking several park regs and the law, he called her on it as it was interfering with an activity he was legally participating in, and she went full Karen. She could have leashed her dog or walked away. She didn’t and she is paying for her foolish mistake.
As for why upload it? Because the stupid woman actually called the cops on him and they have a nasty habit of deleting exculpatory evidence on your phone. The best way to make sure the cops can’t make your video disappear is to make sure it gets publicly uploaded.
