Movies about crimes, crooks, detectives, and scammers are some of the most interesting to watch, as they often detail the steps taken to pull off a crime or catch a criminal. Hollywood has known this for years, and there's no shortage of fictional tales of daring detectives and conniving criminals.
Then there are the movies, documentaries, and series that deal with true crime. For many people, those are far more fascinating because they cover something that actually happened. Typically, these sorts of projects detail solved cases and can include killers' confessions and other material not widely available to the public.
For the most part, all of the crimes have been solved, and the bad guys have been locked away in prison. It's fascinating, but it doesn't do much to help the victims of those real-world crimes. It would be far better if such a documentary or film helped solve a crime instead of only describing them.
It's incredibly rare, but documentaries about various criminals and their crimes have influenced the courts. Cases have been overturned and new evidence has been revealed from a rare interview or background shot. These ten films helped change the outcome of the criminal justice system, and hopefully, they won't be the last.
