Spending Christmas Eve in protest?

So, how effective is this supposed to be?  I've never been to Chicago, but won't the streets there be kinda quiet on the afternoon of Christmas Eve, like most other places?

The Coalition for a New Chicago is planning a Christmas Eve protest on Michigan Avenue. The group announced their plans as the U.S. Department of Justice was to meet with Chicago Police Department officials.

"We're going to pray for our city, pray for our leaders here. But we're also going to march down the street. We're going to be singing, chanting and everything else. But we are going to be a peaceful, disruptive force down on Michigan Avenue from about noon to 5 o'clock that evening," said Pastor Gregory Livingston, founder of a Coalition for a New Chicago.

The group will march on the Magnificent Mile on Christmas Eve in an attempt to engage with the public, Livingston said, under the social tag #BlackChristmas.

The Coalition for a New Chicago, which said they have appealed to President Barack Obama, wants Mayor Rahm Emanuel to resign in the wake of the Laquan McDonald case. They hope the march on Christmas Eve will garner as many participants as the Black Friday march where demonstrators shut down a stretch of Michigan Avenue from the Chicago River to Oak Street.

Some business owners said sales were 25- to 50-percent below projections due to the Black Friday protest.

And why damage businesses' well-being in the process?  I guess their support of your cause doesn't matter.
