Lock them up.
Via CNN:
A total of 214 people have been indicted so far on felony rioting charges in connection with the Inauguration Day protests in downtown Washington.
On the morning of January 20, protests over Donald Trump’s inauguration turned violent when black-clad “anti-fascist” protesters smashed storefronts and bus stops, hammered out the windows of a limousine and eventually launched rocks at a phalanx of police.
Officers responded by launching smoke and flash-bang devices into the street to disperse the crowds. Six police officers were injured and 230 protesters were arrested that day.
