– ISIS really wants to make sure it covers all its bases: A recruitment video released yesterday stars two deaf and mute fighters using sign language. "We, the deaf and mute, direct our message to the Islamic world," the video begins, per Vocativ. The video, titled "From Who Excused (sic) To Those Not Excused," "represents an attempt by the group to recruit other physically or otherwise impaired individuals, as well as demonstrates the multifaceted responsibilities of those in its ranks," a researcher tells NBC News. Those "multifaceted responsibilities" apparently include directing traffic, as that is what the fighters are doing (while heavily armed) in the video.
