Sammy Bull's Grand Jury Primer

Salvatore (Sammy Bull) Gravano, who's set to testify as a government witness in seven trials in the next six months, was a "Shylock's Shylock," with about $2 million "on the street" back in 1989.

That March 17, he passed up the St. Patrick's Day Parade to give his mobster brother-in-law, Edward Garafola, a lesson on how to deal with a grand jury that was looking into loansharking.

"You're called to the grand jury. You gotta take the Fifth. All right so far? Now they give you immunity. What do you do?" asked Gravano as they sat in his construction company office, which had been bugged by the Brooklyn district attorney's office.

When Garafola answered he would "take a contempt" and "go straight to jail," Gravano explained that there was a better way, a way to avoid jail.

"There is three things: common sense is one part, 75% of the answers. Another 10% or 15%, you gotta dance and bob and weave -- one, I didn't remember, I don't think so, or to the best of my knowledge. Okay? Let's say 15%, so we're up to 90%. Ten per cent, you out and out lie."
