How I Caught the Killer

Not Homicide Hunter or The First 48. I just watched an episode where the detectives kept going on about how the victim was "Innocent" because they were a sunday school teacher. This show is full of assumptions and opinions. EG. Every detective I have ever heard says that "You start with the inner circle and work your way out", but apparently, the expert in this show reckons "anybody" could have committed the murder, it could be a stranger knocking on the door". Plus you get to listen to a five minute explanation as to what a polygraph is (like there is anyone on the planet that never heard of a lie detector). Shame, cos it kinda had potential.
