Tastes so good, your character hides under a hood.....

Ernesto X was a notorious American criminal of 1960s. He was regularly imprisoned for robbing, raping and assaulting women. Finally one rape victim identified him positively, and he was arrested. The police then did a tactical mistake, which resulted in a long chain of events that included his acquittal and subsequent arrest and trial, which finally incarcerated him for a long time. However the law was wise enough to learn a lesson from the loophole that had nearly allowed Ernesto to get off scott-free, and since then had incorporated that lesson as an important feature of all legal proceedings against such convicts. Give me the funda. Think of The Shawshank Redemption.
