The police have yet to identify a motive for the attack, but according to two people familiar with the investigation, one of the men that was arrested said that he had watched Islamic State videos and that their motive had to do with the disrespect shown toward Muslims by far-right provocateur Jake Lang, whose demonstration drew the counterprotesters to Gracie Mansion.
