He praised the actions of the police but voiced anger against the rioters comparing their actions to European pogroms in the 19th century. "First Crown Heights, then Washington Heights, then the Golan Heights. This is a Jewish issue. What happened in Crown Heights was not an isolated incident." He commented: "This is not Poland in 1881. It's the United States in 1991!"
Messianism
Before Schneerson's death Butman was active in the movement to crown him as "King Messiah". He was seen as a leader of that movement, organizing rallies to bring about this proclamation. He invoked the recitation of the Yechi slogan in Schneerson's presence without him complaining as evidence that he was indeed the Messiah. He organized the rally on January 30, 1993 that was billed as Schneerson's coronation ceremony. Before the rally he informed the press that "This will be the coronation of the rebbe as Melech haMashiach." Butman was forced to backtrack during the event, announcing that Schneerson appearance did not represent his acceptance of the role of Messiah. He told the 8,000 assembled followers that the event "is not to be interpreted as a coronation." Butman penned a book outlining the religious and philosophical justification for believing that Schneerson was the messiah despite his death in 1995. He made the book freely available online. When the Rabbinical Council of America denounced messianism within Chabad in 1996, Butman went on the offensive telling the press: "Rabbi Shmuel Butman, chairman of the International Campaign to Bring Moshiach, responded to the RCA by saying: "Questions of belief in Judaism are a matter of halachah and should be referred to recognized Torah giants of the generation for a decision" adding that the resolution was "like voting against the rebbe". He was widely viewed as a spokesman of the messianist strand within Chabad. He told the press in December 1994, after Schneerson's death: In later years he has been less outspoken in his messianic beliefs. Since February 2008, he presents the weekly web-based Torah program "Shabbos Night Live" on mainstream Chabad websites COLlive.com and COL.org.il. At the Birchas Hachama ceremony at 770 Eastern Parkway, he was the agreed upon candidate to emcee the rare event.
