>> Former Mayor Rahm Emanuel must testify next week in court.

That's the ruling from a federal judge.

The case concerns allegations that a code of silence among Chicago police officers led to a botched 2018 raid of a back of the yards apartment lawyers for the plaintiffs say that violated the civil rights of a family with 4 children.

It could force a former Chicago mayor to answer questions under oath in open court about alleged police misconduct for the very first time.

Our Heather Sharon joins us now with more.

Heather, take us back to those events back in August, 9th of 2018, what happened in the back of the yards?

Well, at Tate and Cynthia East and say they were at home with their 4 children watching TV and playing video games when they say without warning a Chicago police SWAT team used a pry bar to break down their apartment store and they ordered them out of the apartment while they searched the apartment.

Now, Cynthia Easton says she was forced to leave the apartment even though she wasn't fully clothed.

And Ebony Tate says she suffered a panic attack while trying to comfort her children and not being allowed back into her apartment.

Now police officials and did have a search warrant for that apartment, but it means somebody who didn't live there wasn't there now.

Heather, former Mayor Emanuel who has publicly weighing a presidential run in 2020.

28 first acknowledge a code of silence back in 2015 amid the outcry over the police murder of Laquan McDonald.

Wise is relevant to the trial that's set to start on Monday.

Well, lawyers for the family want to prove that Chicago officials knew that there was a problem with the way Chicago officers were obtaining search warrants and serving search warrants that could help them prove that this amounts to a pattern and practice and that could lead to larger larger verdict for the family and potentially more changes to how search warrants are served in Chicago.

And I can imagine how the family feels because taken we're talking about back 2018.

Now, this isn't the first time CPD has served a search warrant that ended up sparking a lawsuit.

How does it compare to other you've covered?

Well, if what happened to Cynthia Easton, remind you of what happened in Jeannette Young.

You're not alone.

It was 6 months after this ridge that another group of Chicago police officers raided Anjanette Young's house looking for somebody who didn't live there and sort handcuffed her while she was an closed in court.

Her pleas for help.

That lawsuit ended with a settlement of 2.9 million dollars.

It's not clear how much this lawsuit could be resolved for if it doesn't go to trial on Monday
