Worked for a law firm that routinely hired PI’s to investigate workers comp claimants. One particular juicy bust involved a guy claiming a major back injury. PI got a whole days video of him doing a roofing job. Hauling big packs of shingles up a ladder, s**t like that. They went to mediation ready to drop the video on this guy when he shows up in a wheelchair being pushed by his twin brother. The PI had been following the twin all day. Fastest check I’ve ever seen written by an insurance company.
