VIDEO: 2,200 National Guard Troops Ordered Into Ferguson

Gov. Jay Nixon of Missouri ordered more National Guard troops into the embattled city of Ferguson on Tuesday to keep order on the second night after a grand jury decided not to indict a white police officer who shot and killed an unarmed black teenager, reports NBC .

"The violence we saw in areas of Ferguson last night is unacceptable," the governor said in announcing that the National Guard presence would be upped from 700 troops Monday to 2,200 on Tuesday.

"Last night, criminals intent on lawlessness and destruction, terrorized this community," Nixon said at an afternoon news conference. "I am deeply saddened for the people of Ferguson who woke up to see parts of their community in ruins. No one should have to live like this, no one deserves this. We must do better and we will."

On Monday night, at least 12 buildings were burned, police reported looting, and gunfire broke out repeatedly. More than 80 people were arrested in Ferguson and nearby St. Louis. The civil unrest followed the grand jury’s decision not to charge Officer Darren Wilson, who shot and killed 18-year-old Michael Brown on Aug. 9.
