Now, it has the Police Department facing an “operational dilemma” in its laissez-faire handling of the demonstrators, a majority of whom are nonviolent, said Stephen P. Davis, the deputy police commissioner for public information. Top police commanders are set to meet on Monday. “How do you allow the larger group to continue while at the same time prevent the instigators from getting what they want?” he said on Sunday. “Last night is going to have to require some re-evaluation of how we’re doing it.” This is precisely the same problem that the people are having with the police in this country. Interesting that the police response is a thinly veiled threat of more force. Should the people respond in kind?Mr. de Blasio called the eruption of violence “beneath the dignity of New York City.”
