One woman starts recording a guy in Walmart and yapping about him dragging his knuckles. He argues back with her, telling her to stop living her life on the computer. Another woman shows up and gets involved, harassing the guy as well. He tells them off and suggests getting the police involved because they're accosting him.
The first woman is literally following him and recording him in public.
Normal people would continue shopping and be on their way. But people who want to act like a Karen turn on their camera and start harassing random strangers in public.
