Not all criminal justice stories are strictly true. Some are composites of multiple real cases or have fictional aspects woven in to make the story more engaging.
One challenge is the presence of false witnesses. Sometimes people may lie for various reasons like personal vendetta or getting some sort of benefit. For example, in some cases, witnesses have been bribed to give false testimony, which can lead the criminal justice astray from the true story.
Well, it depends. Some criminal justice stories are closely tied to actual events, while others take liberties and create a fictionalized version of reality for entertainment purposes.
It might show the flaws in the system. For example, if there are cases of wrongful convictions, it reflects on how the system can sometimes fail to ensure justice.
Once upon a time, there was a small town. A young man was wrongly accused of stealing. The criminal justice system in that town was slow and bureaucratic. The police arrested him based on flimsy evidence. However, his lawyer was very dedicated. He dug deep into the case, found the real thief who had framed the young man, and finally, justice was served. The young man was released, and the real criminal was punished.
