“I wanted you to see me closer and understand that I would never want to be in your place, having two sons that are going to go to prison,” said Davis, who has struggled openly for two days with the fates of the young men before him.

Adnan, he told them, will go to prison for 10 years.

The scene, unfolding in a packed courtroom in Minneapolis, ended the second of three days of sentencing in the terror conspiracy case, a day that saw harsher sentences — 10 years for two defendants, 15 years for a third — for young men who pleaded guilty but refused to cooperate with government prosecutors.

Farah, 20, the last to be sentenced on Tuesday, was arrested in April 2015 when federal agents rounded up six men involved in the scheme in a series of arrests in Minneapolis and San Diego. He had applied for an expedited passport to leave the United States, but his parents confiscated it when it arrived in the mail. Davis reminded Farah’s father that the action saved his son’s life.

“Your children lied to you,” Davis said. “They lied to you about what they believed and what they were about to do.”
