The video shows the interaction of Milwaukee judge with ice agents before his arrest for an alleged attempt to help the undocumented man

Justice Hannah Dugan had just arrived for work at the County Count of Milwaukee County on April 18, when she was informed that federal agents were waiting outside her courtroom. They were there to stop an undocumented man, Eduardo Flores-Ruiz, who was to appear in front of Dugan on a battery load.

According to federal prosecutors, Dugan came out in the room to question the agents before directing them to the office of the chief of the county in the corridor. Dugan would then have sent a non-public door to Flores-Ruiz to an alleged attempt, according to the authorities, to help him escape the arrest for violations of immigration. An officer who had returned to the corridor – and another who had never gone – said in the criminal complaint that they spotted the man leaving. Flores-Ruiz was captured outside the courtyard building after a brief pursuit on foot.

Dugan, 65, was arrested by the FBI a week later. It is charged in an indictment to two counts of obstruction and concealment an individual to prevent the discovery and arrest of Flores-Ruiz. She pleaded not guilty and her lawyers argue that she is protected from prosecution for official legal acts.

His lawyers described her as arrest “practically unprecedented and” entirely unconstitutional “, according to judicial files.

ABC News obtained, thanks to a request for public files, a video of more than two dozen surveillance cameras at the courthouse, capturing the movements of the judge, the in civilian agents and the targeted man for arrests. There is no audio on surveillance images.

The video is likely to be used by prosecutors and defense lawyers as proof in the Dugan criminal case.

“The video is not conclusive, and I think it tends to support the preconceived ideas that people may have on the case,” said Dean Strang, lawyer for Dugan.

At least seven cameras on the sixth floor – where Dugan’s courtroom is located – captured parts of relevant events.

Six federal agents, in civilian clothes, are seen arriving in staggered pairs shortly after 8 a.m. and exercising positions in the corridor. An agent was sitting directly in front of Dugan’s courtroom.

Dugan arrived through a private entrance to his courtroom at 8:40 am, the video show. Two minutes later, the agents spotted Flores-Ruiz entering the Dugan courtroom through the main entrance.

The judge was then seen a minute later, entering the corridor in his judicial dress, addressing a pair of agents then by directing them and three others in the corridor. According to the criminal complaint, the agents told Dugan that they had an administrative mandate, generally issued by the immigration authorities without signature by a court.

The authorities claim that Dugan would have insisted that the agents needed a judicial mandate and told them to go see the chief judge about their planned operation. Federal authorities allege that witnesses described Dugan as having “conflicting and angry behavior” when she approached federal agents, according to a criminal complaint.

None of the videos published in ABC News shows the interior of Dugan’s courtroom for a few minutes that Flores-Ruiz was there. Prosecutors allege that Dugan never called the case of Flores-Ruiz and led him and his lawyer by a non-public door.

This door, as shown in the videos, was a few meters from the main entrance to the judge’s courtroom and led to the same public corridor. One of the agents had never left the place opposite the courtroom. Another had returned from the office of the chief judge before the release of Flores-Ruiz and followed it.

“If you are predisposed to think that Dugan judge has done something criminal or ice wrongly, you can find support for this preconception in the video. It is not conclusive, but you will feel ratified,” said Strang. “If you start to think that she has done nothing criminal, has done nothing wrong, you will find support for that in the video. For example, she does not seem to be angry. They do not show him a mandate. The man comes out in a few minutes, ten or 15 feet from the place where the agents were waiting for her, and two of them see him coming in the corridor.”

Dugan brought together a great power defense team, which includes the former Advocate General of the United States, Paul Clement, and Strang, who came to the national prominence as one of the defense lawyers presented in the Netflix Docu series, “Making A Murderer”.

“Even if (contrary to what the evidence of the trial would show) the judge Dugan took the measures which claim the complaint, it is clearly legal acts for which it has absolute immunity of criminal proceedings. The judges are authorized to maintain control of their specifically hearing rooms and the palace of justice in general,” wrote his lawyers earlier this month.

Dugan pleaded not guilty during a brief appearance in court on May 15. She remained free of her own commitment and her trial is scheduled for July.
