Authorities are expected to seek charges against organizers of an anti-police-brutality demonstration that descended on the Mall of America during one of the busiest shopping days of the year, Bloomington city attorney Sandra Johnson said today.

Johnson said that potential charges against the organizers could range from disorderly conduct and trespassing to inciting a riot for their role in orchestrating a peaceful, but unsanctioned demonstration Saturday in which between 2,000 and 3,000 people flooded the mall's rotunda, chanting songs and slogans. Twenty-five people were arrested at the rally and cited for trespassing.

Johnson added that her office was working on identifying the protest's leaders through news reports and social media.

"That's standard operating procedure. You want to get at the ringleaders," she said by telephone Tuesday, "to deter any future demonstrations at the Mall of America."

Business owners would not be compensated for lost business after protesters held a small "die-in" in front of several stores, before being cleared out by police officers in riot gear, Johnson said.

In a statement released Tuesday, the group Black Lives Matter Minneapolis said it was "saddened" by the decision to "to misdirect public resources to protect corporate profits instead of supporting justice" for blacks.

"It's clear that the Bloomington City government, at the behest of one of the largest centers of commerce in the country, hopes to set a precedent that will stifle dissent and instill fear into young people of color and allies who refuse to watch their brothers and sisters get gunned down in the streets with no consequences," the statement read.
