SAN FRANCISCO – from www.sfgate.com — Jury selection began in San Francisco today for the trial of former Giants slugger Barry Bonds, who is accused of lying under oath when he denied using steroids.

U.S. District Judge Susan Illston’s clerk swore in an initial panel of 38 prospective jurors for the trial of baseball’s home-run champion, the biggest star in the game’s long history to face felony indictment.

Bonds, 46, is accused of lying when he told a federal grand jury that he had never knowingly used steroids. He has pleaded not guilty.

The judge said she would seat a panel of 12 jurors with four alternates for the trial, which is expected to last four weeks.

The 14 initial panelists seated in the jury box included a carpenter from Foster City, the head of a human rights fellowship program at UC Berkeley and an Antioch retiree with previous jury service.

“It’s hard to make decisions about other people’s lives,” the retiree said.

Another panelist, a retired San Francisco man who said he liked to watch baseball, said he wasn’t eager to serve.

“I would be reluctant to render a judgment against a great athlete like Mr. Bonds, so it may cloud my judgment,” he said.

A Moraga woman who formerly worked as a flight attendant on charter flights for sports teams also said she would find it difficult to be fair.

“I’m still getting over my baseball charters,” she said.

The judge said she would do most of the questioning of prospective jurors. Federal prosecutors and Bonds’ lawyers have been given a total of 60 minutes to ask follow-up questions of panelists.

Prosecutors have six peremptory challenges, meaning they can remove six panelists from the jury without stating a legal reason. Bonds’ legal team has 10 challenges.

Before coming to court today, prospective jurors were asked to fill out a 19-page questionnaire, much of it aimed at learning just how much they know about big league sports and drugs.

The questionnaire contained 63 questions, and 16 of them pertained to sports.

Questions included: Are panelists baseball fans? Are they fans of the Giants? How many baseball games per year do they attend?

Have they heard about baseball’s Mitchell Report, the sport’s investigative history of its steroid era? Did they watch the televised congressional hearings on steroids in sports? Have they heard of the steroids scandal involving the Bay Area Laboratory Co-Operative of Burlingame? And how closely did they follow news reports about Bonds’ case?

Experts said Bonds’ legal team, led by Alan Ruby, may not be able to screen out every person who is aware of steroid scandals in sports. Instead, the task may simply be to find jurors who are willing to put that aside and focus on the evidence.

For the government team, led by Matthew Parrella, experts said one challenge in jury selection might be called the World Series factor. Prosecutors may try to screen out fans who want to give a break to a former star of the hometown team, which in 2010 won its first world championship since moving to San Francisco in 1958.

Saying she is worried that panelists would face harassment, Judge Illston has decided not to reveal the names of Bonds’ jurors until after a verdict is returned. In court, jurors will be referred to by numbers, not names.

Bonds arrived at the courthouse at 450 Golden Gate Ave. at 7:50 a.m. in a black SUV, accompanied by a bodyguard and three other men, and did not respond to reporters’ questions.

The former Giants star was wearing a dark suit. He walked past a fan wearing a black and orange T-shirt with the legend, “If Barry goes to jail then baseball can go to hell.”
