NATS—"Hands up! Don't Shoot!" Ferguson, Missouri, braces itself for a fifth night of protests Thursday, after a police officer shot and killed an unarmed black teenager last weekend. Since then there have been peaceful demonstrations and vigils—as well as episodes of looting, vandalism and violence. Some have accused Ferguson police of using heavy-handed tactics, including tear gas and pepper pellets to break up crowds. Baptist minister Dinah Tatman said she was goaded by one officer.
