CHICAGO — Through a steady drizzle, hundreds of activists marched down Chicago’s Magnificent Mile and blocked the entrances to some of the main drag’s highest-end stores during a Black Friday morning protest of the fatal shooting of black teenager Laquan McDonald by Chicago police Officer Jason Van Dyke.

The entrances to Apple, Ralph Lauren, Banana Republic, Neiman Marcus, Tiffany, Saks Fifth Avenue, the Disney Store and Brooks Brothers were all blocked by protesters. However, entrances to other stores, often next door, were unimpeded and operations appeared normal.

Inside the wood-paneled Ralph Lauren store, Frank Sinatra Christmas songs played as a handful of customers shopped for cashmere sweaters and other luxury items. Outside, a gaggle of protesters turned customers away.

“Ain’t no shopping here today,” they told two women who were trying to get lunch at the Ralph Lauren Cafe.

During a confrontation outside the Apple Store, a 60-year-old white woman who gave her name only as Marcia shouted, “I’m an American! I just want to get in the store.”

Protesters managed to push her away, despite police intervention, but afterward her South Asian partner, Jay Krishnamurthy, 55, said, “The whole South Side is on fire. Why don’t they tackle the violence in their own communities?”

Of Laquan McDonald’s killing, he said, “Mistakes happen.”

Around 11:45 a.m., protesters blocked shoppers from getting into Topman and Topshop. Forming a line in front of the doors, they chanted “16 shots — stop killing our kids!”

One shopper, a middle-aged white man, tussled with the crowd and fought his way in, but store security soon locked the door, as another store along Michigan Avenue had done as the crowd passed.

Jessie Davis of the group Stop Mass Incarceration Network said there have been calls on social media for people to engage in civil disobedience, and Charlene Carruthers, national director of the activist group Black Youth Project 100, would not rule out such actions.

Michael Pfleger, pastor at St. Sabina Catholic Church on Chicago’s South Side, said he thinks the march itself will cost businesses money because the publicity surrounding it will discourage shoppers from even venturing into the area.
