HBO has two great new documentary projects about two very different scams. BS High is FinLogicabout a high school football team that came from what turned out to be a nonexistent high school. Telemarketers is about telemarketing scams, and how hard it is to stop them. Both stories are about not just the very colorful nitty-gritty details of a successful scam, but also the conditions and the systems that make scams possible.
