At least four police officers in St. Louis, Missouri, were shot and another was killed in Las Vegas on Monday night, according to multiple reports.
The shootings come amid days of protests and violent riots in dozens of cities as law enforcement struggles to enforce curfews and prevent looting. Early reports say a U.S. Marshall was killed in Las Vegas after being shot in the head outside a federal courthouse and police have reportedly confirmed he is still on life support. Four St. Louis officers were also shot, according to multiple local reports, but all remain conscious and are expected to recover.
