Milwaukee was on edge until this month, when Spengler and two other officers, Daniel Masarik and Jon Bartlett were arrested for the felony battery of Jude. All entered pleas of not guilty.
None of the three would talk to "Primetime Live" on camera. But Spengler invited co-anchor John Quiñones into his home to assert he was not guilty as charged.
At a pretrial hearing this month, police Officer Joseph Schabel broke the code of silence. He was on duty the night of Spengler's party and says he witnessed the three defendants beating Jude right in front of him.
Schabel and his partner will be the key witnesses for the prosecution, but the district attorney is urging other officers to come forward with information. Milwaukee police are conducting an internal investigation.
Jude is calling for justice. "I want more officers to come forward. Speak the truth," he said.
Meanwhile, he expressed gratitude that Brown and Antonissen were with him that night -- even though they had only known him for a few hours.
"Without them two calling 911, I wouldn't be here," he said. "They're angels on my side."
