Police fire tear gas at protesters in Wauwatosa, Wisconsin

Police fire tear gas at protesters in Wauwatosa, Wisconsin, on Wednesday night, October 7, 2020. Violence erupted after a judge ruled that police officer Joseph Mensah will not face criminal charges in the shooting death of 17-year-old Alvin Cole. Milwaukee County District Attorney John T. Chisholm said there was ''sufficient evidence" that the officer believed using deadly force was appropriate for the situation. The unrest was backed by the Black Lives Matter (BLM) movement, which has been behind similar rallies across the U.S. following the death of George Floyd in Minneapolis, Minnesota, on May 25.
