Good legal help is where you find it. Cochran broke no laws or codes of legal ethics (such as they are) and represented his client to the best of his abilities. If you are deeply in trouble, do you want the lawyer to argue for you, or get you off? Personally, I would like to have the lawyer that will get me off in front of the jury I am facing, whether I did it or not, as I have the right to legal defense in our adversarial system of justice. If found not guilty by the jury, nobody elses opinion matters.
