This documentary’s story line wouldn’t be believed, at least by me, if it had been presented as fiction. But this really happened: William Lawrence, a former sheriff, established in Utah one of the state’s first fully outfitted, specially trained SWAT teams – one of which, many years later, ended up killing his son-in-law in a dramatic confrontation. After that, Lawrence looked into that incident, and others, building a hefty dossier regarding controversial police-related shootings. Check local listings.
