New York City Mayor Bill de Blasio came under an onslaught of criticism on Tuesday night when he tweeted his reaction to the overcrowded funeral procession for a rabbi from the Satmar Hasidic sect of ultra-Orthodox Jews. The first tweet called the crowd that had in South Williamsburg, in violation of statewide bans on gatherings of 10 or more people, “unacceptable.” But de Blasio’s subsequent message sent Twitter into a spasm of rage because it began, “My message to the Jewish community, and all communities, is this simple: the time for warnings has passed. I have instructed the NYPD to proceed immediately to summons or even arrest those who gather in large groups.”
