ROBERT SIEGEL, HOST:
This has been, by most accounts, a strange trial. There was, for example, the giggle gang, with more than a week of deliberation attention had turned to a merry band of alternate jurors, four of them who wore the same colored shirts to court each day. As NPR justice correspondent Carrie Johnson reports, there is considerable precedent for shenanigans in the jury pool.
CARRIE JOHNSON, BYLINE: Reports that a young alternate juror had been flashing smiles at John ricocheted far beyond the courtroom in Greensboro, North Carolina. Edwards in on trial for campaign finance violations for trying to hide his pregnant mistress during a presidential campaign.
HANK ASBILL: There were a number of stories over the years, but I mean, I've never seen anything like this.
JOHNSON: Hank Asbill has been a defense lawyer for 35 years, long enough to remember when the prominent attorney defending William Kennedy Smith in 1991 on rape charges, met and later married a member of that jury. But Asbill says the color-coded T-shirts worn by the Edwards jury alternates represented something new under the sun.
ASBILL: I've never seen this kind of conduct by alternates. I think that that's unusual and strange. It's also unusual for alternates to be around the courthouse.
JOHNSON: Usually, he says, a judge will let alternates go about their daily lives during deliberations and call them back to court if one of the regular jurors gets sick or drops out. And that's what finally happened yesterday, when the trial judge in the Edwards case let them go home, on standby. Asbill thinks those alternates were acting out because they just got bored.
After all, jurors are only human. And in high-profile cases, the microscope on jurors can magnify lots of spots, even ones that aren't really there. Take the case of Dennis Kozlowski, the CEO of Tyco. Back in 2004, he was on trial for looting the company to pay for shower curtains, umbrella stands and a $2 million birthday bacchanal for his wife. Austin Campriello was a defense lawyer in the case.
AUSTIN CAMPRIELLO: There came a point in time where the jury was being excused, and one of the jurors was walking across the courtroom to go to the exit, and the prosecutors believed that they saw her give the defense table an okay sign.
JOHNSON: Tabloid reporters identified the elderly juror and dubbed her the holdout granny. Campriello says the CEO's legal team didn't see it that way.
CAMPRIELLO: We don't think she was sending us a message. We think she was flipping back her hair.
JOHNSON: Whatever the case, the juror eventually told the judge she got threatening mail. So the judge declared a mistrial, after nearly six months, and the case had to start all over again, with a new jury. Lots of trials have ended in disgrace lately because jurors are emailing, tweeting or otherwise social networking.
Earlier this year, a Florida man got three days in lockup for friending a female defendant on Facebook. Former prosecutor Steve Cohen remembers he was flummoxed by a more old-school kind of jury communication. After a long wait for a verdict in a triple homicide case, Cohen says, came this disconcerting development.
STEVE COHEN: We got a note from the foreperson. And the note said, would it be possible for us to render a verdict and then the court hold the defendant and his family in the courtroom for one-half hour?
JOHNSON: The judge followed up and learned that several jurors used the same New York subway route as the defendant's family.
COHEN: And it turned out they wanted a head start so that they could get home after they rendered a verdict. At that point, we knew they were voting guilty.
JOHNSON: So maybe that's a lesson of not reading too much into jury notes before you know what's going on.
COHEN: I take from that, that my ability to guess anything when it comes to a jury is nonexistent.
