My wife watches police "procedural" stories (Law & Order, CSI, NCIS, etc.). I've long thought that some of their plot lines would make for interesting "what if" training cases for real cops.
Case studies of actual investigations - what worked, what didn't, what the big break was, etc - are not uncommon in law enforcement academies and training.
When you watch stuff like CSI and Law & Order, their criminal investigation stuff is often about as accurate as their high tech and computer science stuff.
