MADISON, Wis. — Federal prosecutors on Friday charged a Black man whose arrest triggered a violent protest in Wisconsin's capital city with extorting local businesses. Police arrested 28-year-old Devonere Johnson in Madison on Tuesday after he walked into Cooper's Tavern near the state Capitol building with a megaphone and a bat. The arrest sparked a protest later that night that saw demonstrators tear down two statues outside the Capitol building and assault state Sen. Tim Carpenter on the Capitol lawn.
