Kenosha calm after nights of unrest -sheriff

"Last night was very peaceful," Kenosha County Sheriff David Beth told a news conference. "Hopefully, we are over the hump of what we have to face."

Kenosha's first orderly night since the protests began came after Wisconsin Attorney General Josh Kaul identified Rusten Sheskey as the officer who on Sunday afternoon fired seven shots at the back of Jacob Blake after the 29-year-old opened his car door. Kaul also said investigators found a knife on the floor of Blake's car.

In Kenosha, after three nights of civil strife - including arson, vandalism and shootings that killed two people on Tuesday night - calm took hold. About 200 protesters defied a curfew and marched peacefully through city streets, chanting, "Black lives matter," but law enforcement officers kept a low profile, and armed militia members were notably absent.

Prior nights drew an array of rifle-toting civilians, among them 17-year-old Kyle Rittenhouse, who was arrested on Wednesday on homicide charges in connection with Tuesday night's shootings.

Rittenhouse, a police supporter, was arrested at his home in Antioch, Illinois, about 20 miles (30 km) away.

The American Civil Liberties Union on Thursday called for the resignations of Sheriff Beth, Kenosha Police Chief Daniel Miskinis and Kenosha Mayor John Antaramian, arguing they had mishandled the response to Blake's death and the resulting unrest.
