Expert: Picking a jury for Anthony case will be tough

Prosecutors in the Casey Anthony murder case should learn this week if air samples from her car will be allowed as evidence.

Meanwhile, next month's jury selection may be strewn with land mines.

"This will be one of the most difficult cases in the history of Florida to find a fair and impartial jury," said Kendall Coffey, a Miami attorney, who's written a book about trying cases in the court of public opinion.

Coffey says Casey's already been convicted by the public at large.

"Well, the attorney will ask all the right questions, but sometimes jurors will not be as candid as they should be in a super-sized case like this," said Coffey.

He says there's the danger of a stealth juror, someone whose ambition is to write a book about the trial, go on TV and get their 15 minutes of fame.
