MILWAUKEE (CBS 58) -- Judge Hannah Dugan's defense team rested its case Thursday morning, Dec. 18, after calling four witnesses to the stand. Dugan did not testify in her own defense. Closings arguments are underway now. 

The defense moved quickly and finished by mid-morning. After an early lunch break, the prosecution began its closing argument. The belief is the jury will begin deliberations by mid-afternoon. 

All along, Judge Dugan's defense has tried to show she was simply following orders when she directed the federal agents out of the hallway and into the chief judge's room. 

Though no official policy was in place, a draft policy was, and the defense argues that's what Dugan was following. 

On the witness stand, fellow Milwaukee County Circuit Court Judge Laura Gramling Perez recounted a lengthy email chain between the judges that occurred over several days.

It discussed recent ICE activity, uncertainty with how to handle it, and a desire for a policy to govern those interactions. 

Judge Gramling Perez wrote it sounded like other recent detentions fell within the law. 

But, Gramling Perez said, "I would strongly advise we develop a court-wide policy governing ICE actions." 

The defense says Dugan was trying to comply with shifting rules and the clearest evidence of her state of mind is an email she sent 10 days before the incident. 

Dugan wrote it would be helpful to identify concerns and develop a consistent set of protocols. 

She added in the email, "We are in some uncharted waters with some very serious and even potentially tragic community interests at risk." 

To show the seriousness of the situation back then, another witness -- Judge Katie Kegel -- read an email she sent that said, "People have been snatched up out of my gallery while waiting for their hearing." 

And showing there was uncertainty, public defender Maura Gingerich said she took photos of the agents in the hallway that day so that her manager could ask the chief judge for further guidance. 

The last witness was former Milwaukee Mayor Tom Barrett, who has known Dugan for more than 50 years.

Barrett testified to Dugan's character saying, "I think she is extremely honest." But the prosecution pointed out he was not at the courthouse April 18. 

The prosecution is unsure how long its closing arguments will take, but the defense will go immediately after. 

Following a short rebuttal, jury instructions will be read and then deliberations will begin. 

There is a belief a verdict could come sometime Thursday afternoon.
