CBS reports:

Alton Logan doesn't understand why two lawyers with proof he didn't commit murder were legally prevented from helping him. They had their reasons: To save Logan, they would have had to break the cardinal rule of attorney-client privilege to reveal their own client had committed the crime. But Logan had 26 years in prison to try to understand why he was convicted for a crime he didn't commit....

Lawyers Jamie Kunz and Dale Coventry were public defenders when their client, Andrew Wilson, admitted to them he had shot-gunned a security guard to death in a 1982 robbery. When a tip led to Logan's arrest and he went to trial for the crime, the two lawyers were in a bind. They wanted to help Logan but legally couldn't....

The lawyers did get permission from Wilson, to reveal upon his death his confession to the murder Logan was convicted for. Wilson died late last year and Coventry and Kunz came forward. Next Monday, a judge will hear evidence in a motion to grant Logan a new trial.

I'm not a legal ethics expert, but my understanding is that there is indeed no exception from attorney-client confidentiality in such cases. (If a client tells you that he intends to commit a crime in the future, you may be able to turn him in, but not when he admits that he has committed a crime in the past.) And I can certainly understand the reasons for such a confidentiality rules, whether for lawyers, priests, or psychotherapists. But, boy, they surely do yield a very troubling result in a case such as this one.

Thanks to Paul Milligan for the pointer.

Some reactions to my "a classical ethical bind for lawyers" post suggested that the ethical question was easy: The lawyers whose client had said he committed a murder should have revealed that information in order to free the person who was wrongly imprisoned for that murder, even assuming that would have meant disbarment or long-term suspension for violating lawyer-client confidentiality. If they didn't do this, they'd be acting unethically.

But even assuming that the underlying confidentiality rule is unsound, surely it's not so clear that people have an ethical duty to save another's life at such great expense. My guess is that if you spent $10,000, you could likely save the life of some sick child in Africa; if you spent $50,000, I imagine this would be even likelier (and perhaps the number is actually a lot less). If you donated a kidney — which will expose you to a roughly 0.03% risk of death, and a slightly larger but still very small risk of complications — you could dramatically reduce a roughly 20% or more risk of death for someone on the kidney waiting list (since that's how risky it is for him to be on long-term dialysis while he's waiting for a new kidney). If you find someone who's near the tail of the waiting list, you might reduce a still greater risk. Yet most of us wouldn't say, I think, that it's really your ethical obligation to run such a risk, or bear such a cost, to save a stranger's life.

Likewise, I don't think that it's really your ethical obligation to lose what is likely hundreds of thousands of dollars in future income, by giving up a profession that you spent over a hundred thousand dollars to train for. You might deserve credit for making such a choice (assuming we conclude that the ethical rule you're violating is indeed unsound). But that's different from saying that you have an ethical duty to make that choice.
