Atlanta, Aug 25: Three dozen lawyers have offered to represent John Mark Karr - for free in many cases - against allegations he killed 6-year-old beauty Queen Jonbenet Ramsey. The tug-of-war among defense attorneys over one of the biggest criminal cases in recent years, one that has stoked interest because of perceived flaws in the prosecution's case, raises questions about ethics and who has Karr's best interests in mind. "There's something inherently wrong in hiring a lawyer who is volunteering to do it for publicity," said Connecticut Attorney Mickey Sherman, whose high-profile clients include Kennedy cousin Michael Skakel. Two California attorneys say they have been retained to represent Karr, but another who was with him at his only court hearing in the case said previously that Karr wanted a Colorado public defender.
