While this is not exactly a major case or a major crime at all, prisons everywhere have people who plead guilty to crimes they did not commit, not to mention people who were convicted of crimes they did not commit...If you think the monthly (or so!) rate of US death row inmates, the worst of the worst criminals, who are still being sprung from jail on a regular basis (even after 20+ years of automatic appeals have been exhausted with no luck) if they happen to be lucky enough (very small %) to have some new evidence or technology or law change or fix the story with someone working hard on the outside for years, then imagine being caught up in the other huge % of countries with completely corrupt, disfunctional, politically-driven, useless and blatantly unfair legal systems...not the the US system is free of those things!
