What If Your Death Row Client Refuses to Allow You to Offer Exculpatory Evidence?

Your client is charged with the first degree murder of a grocer and his son, and the prosecution's key evidence is your client's shotgun wound.  Your client has a plausible explanation for the wound but refuses to let you offer it. The black letter law says this is not a hard call -- you can't do it. You can violate attorney-client privilege to save somebody else's life, but not your own client's. This is true even if it's 1915, your client's name is Joe Hill, and the whole world is watching.  According to this story in the New York Times, a new book about the radical activist Joe Hill to be published this week makes a strong case for Hill's innocence.  Cue Joan Baez.
