Missouri Gov. Jay Nixon declared a state of emergency and implemented a curfew in Ferguson in the wake of the shooting that left Michael Brown dead.

Nixon explained that after hours of peaceful protesting last night, small groups took to the streets with the intent to commit crimes and harm people, calling it “unacceptable.”

“We will not allow a handful of looters to endanger the rest of this community,” he said.

The governor said he has been in touch with local leaders about protests and riots.

“I share their frustration and conviction that we cannot allow the ill will of the few to undermine the good will of the many,” he said.

Nixon said he is “committed to making sure the forces of peace and justice prevail,” but that Ferguson must first have and maintain peace.

“This is a test. The eyes of the world are watching. This is a test of whether a community […] can break the cycle of fear, distrust and violence and replace them with peace, strength and ultimately justice. It will not happen in one night, but that is where we will start,” he said.

The curfew will run from midnight until 5 a.m., effective tonight.
