The "protest" was meant to intimidate the family and neighbors of Bob Kroll, president of the Minneapolis police union.
One leader of the demonstration was Democratic politician John Thompson, who recently won the primary for a safely Democratic seat in the Minnesota House. Thompson shrieked obscenities at community members, declaring that the "f***ing Grand Wizard [of the Ku Klux Klan]" lived in the town:
At another point in his tirade, Thompson threatened the locals, screaming "You think we give a fuck about burning Hugo down?" and "I didn't come here to be peaceful." He also said that "blue lives [i.e. police] don't mean shit to black people."

Thompson was recently endorsed by Minnesota governor Tim Walz, who said "His fierce advocacy and commitment to his community is exactly what's needed in the state legislature right now."
Thompson's behavior would seem to run afoul of Minnesota's law against disturbing the peace, which among other things prohibits "Inciting violence by using offensive language in public or by shouting."
