Who is that guy with the video camera?
The insurance company wants to keep claims paid to a minimum. If they can videotape you doing something that indicates your injury is not as serious as you claim, like playing softball or water skiing, for example, they may try to use this in a proceeding to stop paying you. If they are successful, they are likely to “save” some money. The guy with the camera is a private investigator, hired by the insurance company. Use common sense. If you know you are being spied on, call a lawyer.
