I've heard the same as you. If I or a loved one was in a world of trouble, I would want would the best possible legal representation. One of the reasons my daily "to do's" includes stay the F%$k out of trouble.
I also know every lawyer- from the cub who just passed the bar to the uber-cuddly Alan Dershowitz-believes that due process and every person's right to a fair trial supersedes anything. ANYTHING. Anything like, you know, every fiber in their lawyerly being KNOWS the guy sitting across the table from them is the same guy who molested and carved his wife and children into roughly 4,486 pieces.
Better a bazillion guilty people walk than a single innocent getting locked up, right?
