Atlanta: 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 defence 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. Larry Garrison, a producer Karr's family hired to ferret out book and movie deals, says they want a big-time lawyer for the job. Some three dozen lawyers from around the country have already offered their services, many at no cost.
