This one was a stretch of my suspension of disbelief that someone who committed a crime, but allegedly not murder, goes after the jury that sent him away rather than his partner in crime (who allegedly did commit the murder).  Didn't one theme song say "Don't do the crime if you can't do the time"?  Also, at the end I agree with Mike about the friend figuring out how a conversation went.  It was an okay story for me, but not the best.
