Good news for OJ Simpson on the legal front. Simpson, standing trial in Las Vegas for robbery and kidnapping stemming from a 2007 altercation with memorabilia dealers, received support yesterday from a surprising source: Prosecution witness Alfred Beardsley. Beardsley, one of the two dealers alleged to have been victimized by Simpson and a group of others, expressed skepticism as to the authenticity of a key piece of evidence, a recording of the altercation secretly made by one of the men who accompanied Simpson. Beardsley testified that many parts of the event appear to have been removed and refused the prosecution's request that he authenticate the tape as a true recording of the event as it unfolded.
