Jury selection in O.J. Simpson’s robbery and kidnapping trial continues, getting more and more difficult.

Defense lawyers are now struggling to seat a racially diverse panel with un-biased jurors, who were not affected by Simpson’s long-ago “Trial of the Century.”

“What happened then, happened then,” Clark County District Court Judge Jackie Glass told prospective jurors.

Glass told the potential jurors that if they were there thinking they were going to punish Simpson for what happened many years ago, then “this is not the case for you.” She added that she didn’t want panelists who intended “to become famous and write a book and be on TV.”

Glass stopped short of allowing Simpson’s attorneys to ask the potential jurors whether they considered the football star a murderer. But she dismissed two people who said they couldn’t get past Simpson’s 1994 trial.

In a discussion that happened outside the presence of the jury prospects, a lawyer for Simpson co-defendant Clarence "C.J" Stewart raised the issue of race, saying that there were too few blacks in the Las Vegas jury pool to fairly deliberate the fate of the two defendants, the Associated Press informs.

Glass rejected his request of enlisting more black jurors.

Simpson is accused of robbing two sports collectible dealers at gunpoint at the Palace Station Hotel & Casino last September. He claims that he was trying to recover stolen mementos and said he did not know that any of his followers were armed.

Simpson and his co-defendant Stewart each face 12 charges, including kidnapping and armed robbery. If convicted, the two could face a potential life sentence.
