[Santa Ana, Calif. attorney] Daniel J. Callahan took respect for a jury to a whole new level. His client manufactured blood analyzers used to diagnose illnesses, and it claimed it was defrauded by a firm that supplied its circuit boards. The jury returned a verdict of $934 million. After it was over, he invited jurors to a party at his home. And sent limousines to pick them up.
“Oh my God,” some of his friends said. “You did that?”
“Yeah,” he told them. “It’s legal.”

When his client’s recent rape trial ended in a hung jury, defense lawyer Joseph G. Cavallo decided to hire some of the jurors to get advice, to the tune of $50 an hour. While hiring a juror is not a crime or prohibited by professional conduct rules in most states, ethicists disagree about the propriety of the ever more common practice.”
