WASHINGTON (AP) — With cities wounded by days of violent unrest, America went into a new week with neighborhoods in shambles, urban streets on lockdown and shaken confidence about when its leaders will find the answers to control the mayhem amid unrelenting raw emotion over police killings of black people. All of it smashed into a nation already bludgeoned by a death toll that surged past 100,000 from the coronavirus pandemic and unemployment that soared to levels not seen since the Great Depression. Arrests have topped 4,400 according to an Associated Press tally.
