An inauguration protest in Washington, D.C., turned confrontational on Friday, as several hundred black-clad protesters broke windows and police responded with pepper spray and a concussive device.
The interim chief of the Metropolitan Police Department, Peter Newsham, said 217 protesters have been arrested, and 6 officers sustained minor injuries.
Newsham, in a late afternoon news conference, said those arrested will be charged with rioting. He added that most of the protestors were peaceful, but that a small group of people seemed intent on creating mayhem.
"They began to destroy property and throw objects at people and through windows. A large percentage of this small group was armed with crowbars and hammers. Vehicles and store fronts were damaged. ... [It] appeared the activities of this small group were organized and intentional," he said.
