I think Mesereau was entirely right to file this motion. Jay Leno is not an expert on the details of the prosecutions case, and has no more knowledge of Michael Jackson's guilt or innocence than anyone else who reads a newspaper. Allowing him to profess his opinions would only be prejudicial, and not probative. Jay Leno had specific information about a phone call he received from Gavin Arvizo. That is the only information he should be allowed to testify to in court. His opinion about other aspects of the case is irrelevant.
