"I know what I did was dangerous," said Hayne, tattoos showing from under a short-sleeve blue jail suit and his buzz cut a marked difference from the long hair in his arrest mug shot.
The three co-defendants who pleaded guilty did so without plea deals. They were sentenced previously to eight- to 11-year terms, shorter than the government had recommended.
The three have appealed their sentences as too harsh for a crime that didn't hurt anyone. Hayne's attorney, Michael O'Shea, said he doubted a sentence appeal would help Hayne much, since the crime carries a mandatory minimum of five years.
O'Shea said Hayne deserved less prison time than the others because his plea and offer to testify had led to others pleading guilty within six weeks. Hayne's testimony showed a plot was evolving even before the involvement of an FBI informant whose work led to defense entrapment claims, O'Shea said.
The judge acknowledged the key role Hayne's guilty played, saying it "did work for the great benefit of the government."
Hayne's mother watched the sentencing and later said only that his family loves him.
