O.J. Simpson is in back court again, this time hoping to make the case that bad legal advice from his former lawyer is what got him convicted in 2008 for robbery. Simpson is currently serving a nine- to 33-year sentence for the 2007 armed robbery of two sports memorabilia dealers in Las Vegas. The former NFL superstar, who was acquitted of his wife's murder in 1995, is arguing that his ex-lawyer, Yale Galanter, actually approved of the robbery the night before it took place and then purposely did not do everything he could have to defend him. Galanter will testify on his own behalf Friday. This is the second time Simpson has appealed his robbery sentence. If rejected again, he'll be eligible for parole in five years.
