Outrage, frustration and grief are driving hundreds of protesters into the streets of Minneapolis, Los Angeles and St. Paul, Minn., after the death of George Floyd, an unarmed black man whose arresting officer was recorded kneeling on his neck for minutes on end.

Over the past few days demonstrations in Minnesota have evolved from peaceful cries for justice into violence and destruction.

Floyd's arrest and final minutes of his life were captured in multiple videos that are circulating widely on social media. In all versions, Floyd is pinned to the ground with his hands handcuffed behind his back. The knee of a police officer is crushing his neck, as another officer stands a few feet away. He is watching, seeming unfazed as the 46-year-old cries, "I can't breathe."

Angry crowds have looted businesses and burned buildings. Meanwhile, law enforcement has met the civil disorder with clouds of tear gas.

The unrest prompted Minnesota Gov. Tim Walz to activate the National Guard on Thursday to bring calm to the streets.

"It is how we express pain, process tragedy and create change," he said about the act of protesting.

But he noted the urgency in responding to local leaders' calls for the National Guard "to protect peaceful demonstrators, neighbors and small businesses in Minnesota."

"It is time to rebuild. Rebuild the city, rebuild our justice system and rebuild the relationship between law enforcement and those they're charged to protect," Walz added.

Lt. Gov. Peggy Flanagan added that the purpose of the National Guard is to ensure safe demonstrations and to protect small-business owners.

"The anger and grief of this moment is unbearable. People deserve to be seen. People deserve to be heard. People deserve to be safe," Flanagan said.

"While many Minnesotans are taking extensive safety precautions while exercising their right to protest, the demonstration last night became incredibly unsafe for all involved," she added.
