The equal and opposite of the Cop Show and Police Procedural, the Criminal Procedural is a type of Crime and Punishment Series that focuses on people who are on the wrong side of the law, and especially their present-day transgressions of it. Examples often focus on certain types of criminals:

Con Men and Gentlemen Thieves are the most popular, since it's easy to make them sympathetic to the audience by making their victims rich and greedy. They are also usually charismatic and attractive. Their shows are usually light in tone and there will almost certainly be one episode where they actually help the police to take down a violent (and therefore "bad") criminal. There may be a recurring police officer who tries (and fails) to capture the protagonists, or who coerces them into helping him out with his investigations.
