A judge sentenced Jon Bartlett, 36, to 17 years and four months in federal prison. The sentence also includes three years supervision and payment of $16,365 in restitution.
Daniel Masarik, 27, was sentenced to 15 years and eight months in prison.
Bartlett and Masarik were convicted with another former officer for taking part in the beating of Frank Jude Jr. outside a housewarming party in October 2004.
The third former officer, Andrew Spengler, 28, was scheduled to be sentenced later Thursday.
Bartlett was the ringleader in the attack, Jude wrote in a statement submitted to the court Thursday. Jude feared for his life and had hoped U.S. District Judge Charles Clevert would give Bartlett the maximum 20-year sentence, he wrote.
"You and your fellow police officer friends attempted to kill me and take my life," he wrote. "Mr. Bartlett, you are a disgrace, a disgrace to all police officers, and every public official in the world."
Bartlett apologized to Jude in court Thursday, but he stood by his claim that he had to deal with unruly suspect.
A state jury had already convicted Bartlett of calling in a bomb threat to his former police district station, resulting in 4 1/2 years in prison. He later pleaded guilty in federal court to trying to buy a semiautomatic rifle and pistol, 875 bullets and high-capacity magazines for each weapon while he was facing felony charges. He was sentenced to 18 months in prison in that case, reported the Milwaukee Sentinal-Journal.
A federal jury determined in July that the three violated Jude's civil rights and conspired to assault him while acting as officers. Officer Ryan Packard was acquitted of federal charges.
The trial is the second round in a case that has haunted Milwaukee. The three men were acquitted of most state charges by an all-white jury in April 2006, angering the community. Federal authorities filed the civil rights charges six months later.
In the days after the state trial, black and white residents, including the mayor, expressed their outrage at community meetings. Up to 2,000 people marched from the Milwaukee County courthouse to the federal courthouse.
Jude, 29, said he had been at a party on Oct. 24, 2004, when a group of white men who identified themselves as off-duty officers kicked and punched him, put a knife to his throat and jammed a pen in his ears as he begged for mercy. Jude said he heard Spengler call him a racial slur.
"They came close to killing Mr. Jude," said his attorney, Jonathan Safran. "They caused him serious permanent physical injuries and mental injuries he and his family will have to deal with the rest of their lives."
Jude said the confrontation began as he and a friend were leaving the party, when a group of men surrounded their truck and dragged him out, accusing him of taking Spengler's badge. No badge was ever found.
The community has cried injustice since the Milwaukee Journal Sentinel published a front-page photo in February 2005 showing Jude's swollen, misshapen face just after the beating.
Reading a statement on behalf of Jude, attorney Jonathan Saffron called Bartlett's actions "those of a terrorist."
"You violated my civil rights and you attempted to kill me. You took my life. You are a disgrace to the police uniform," but added that he would pray for Bartlett's soul, reports the Journal Sentinal.
The police department disciplined 13 officers after the beating, including nine who were fired. Two of the fired officers won back their jobs, including Packard after a 20-day suspension.
Four others have pleaded guilty to similar federal charges. One has been sentenced to two years in prison and another a year in prison along with a year of probation, a fine of $3,000 and 100 hours of community service.
Two others are scheduled for sentencing Dec. 6.
