A week of rising unrest across the country burned through Oakland and San Jose on Friday night as thousands of demonstrators rallied against police brutality in heated demonstrations that began peacefully, then spiraled into chaos, with crowds setting fires, smashing windows and looting stores, and heavily armed law enforcement confronting protesters with tear gas, rubber bullets and flash-bang grenades.

In Friday’s most severe violence, a gunman opened fire on two federally contracted security officers in downtown Oakland, killing one and critically wounding the other in an act federal authorities described as “domestic terrorism.” But while the federal complex was one of dozens of buildings damaged during the protest, it remained unclear Saturday whether the shooting had any link to the demonstration that was raging just steps away over the killing of George Floyd in Minneapolis.
