Minneapolis Mayor Jacob Frey, who has been steadily and resolutely calling for justice following the police-involved death of George Floyd, is speaking out once again following a night of violence in the city, acknowledging residents’ anger and sadness as a result of systemic injustices that have existed in the country since slavery.

“The emotion-ridden conflict over last night is the result of so much built up anger and sadness,” Frey said during a news conference.

“Anger and sadness that has been ingrained in our Black community, not just because of five minutes of horror, but 400 years.”

Frey demanded that non-Black communities acknowledge and understand the anger and sadness of Black residents.

Frey explicitly noted that the technique used on Floyd was prohibited, condemning the officers for their actions.
