The trade-off that everyone is conveniently forgetting is that a multitude of criminals are also being convicted based on insufficient evidence. Any thorough skeptic is unpleasantly surprised when he applies the same standards to which he holds, say, psychological research, to what happens in the court of law and concludes that a great many convictions do not stand up to close scrutiny. This becomes obvious in cases of high-profile criminals: when all eyes are on a case, it gets much harder to convict someone.
