I think most defense attorneys honestly believe the principle that says, 'Better 10 guilty go free than even one possibly innocent person be convicted.
I read in the newspaper that the Catholic Church finally decided that it had been theologically improper to try to convert the Jews. Whoops! Sorry for all those inquisitions, crusades, and autos-da-fe. Previous popes were wrong - infallible, perhaps, but wrong.
On television and in the movies, crimes are always solved. Nothing is left uncertain. By the end, the viewer knows whodunit. In real life, on the other hand, many murders remain unsolved, and even some that are "solved" to the satisfaction of the police and prosecutors lack sufficient evidence to result in a conviction.

I don't think the law exists to arrive at the truth. If it did, we wouldn't have exclusionary rules, we wouldn't have presumptions of innocence, we wouldn't have proof beyond reasonable doubt. There's an enormous difference between the role of truth in law and the role of truth in science. In law, truth is one among many goals.
In today's distorted world of 'human rights,' truth takes a back seat to ideology, and false claims - especially those that 'support' radical ideologies - persist even after they have been exposed.
Ed Koch will never "rest in peace." That was not his way. He was always nervously squirming, while making others squirm as well. Comfort was not his goal. He understood that to be a proud and assertive Jew meant never being able to leave a sigh of relief and say "it's over, we are at peace, we can now put down our guard and relax."
We don't have an Official Secrets Act in the United States, as other countries do. Under the First Amendment, freedom of the press, freedom of speech, and freedom of association are more important than protecting secrets.
