It's been almost four years since Chicago police officer Jason Van Dyke shot Lequon

McDonald. Today he goes on trial for murder. A coalition of activist groups plans to be outside the courthouse every single day of the trial.

One of the organizers is Will Calloway, the man who helped get the McDonnell Dashkim video released to the public.

It's important that we have observers inside the courtroom, but it's also important to us that the community

and the city and the nation, the world, at that point see us out here demand

of justice for Laquoans. So it's important us that we occupy this space and

that it's going to continue to build about a thousand over the weeks to come.

They've got a permit and they say they plan to occupy the whole block across the street

from the courthouse.

And they say they'll set up screens to allow people to watch the trial,

to see how this whole thing finally plays out.

From W.B.E.Z Chicago and the Chicago Tribune,

this is 16 shots, the police shooting of Lacan McDonald.

I'm Jen White.

Over the last four episodes, we've talked about the many ways the Lacan

McDonald shooting has shaped the city of Chicago, an al-state police superintendent, sweeping reforms in the police department.

And just yesterday, we brought you news if Chicago's mayor deciding not to run for another term as the trial begins.

Now we want to zoom in and break down what to expect in the courtroom. Chip Mitchell is a WBEZ reporter who's covered this case since officer

Van Dyke was charged almost three years ago. He's going to walk us through the

main players in the Van Dyke courtroom battle, the judge, the prosecutor, and the defense attorney.

So Chip, first, jury selection starts today.

What are we expecting?
