Days after a jihadist had made violent threats against him, late-night comedian David Letterman tightened security at the Manhattan theater where he tapes his “Late Show.”
A source told the New York Post Friday that additional security precautions were taken at the Ed Sullivan Theater after a Muslim extremist called for Letterman’s tongue to be cut out on Shumuka al-Islam forum, a popular Internet destination for radical Muslims.
“Is there not among you a Sayyid Nosair al-Mairi … to cut the tongue of this lowly Jew and shut it forever?” a user identified as Umar Al-Basrawi wrote, referring to El Sayyid Nosair, who was convicted of the 1990 killing of Jewish Defense League founder Meir Kahane. Letterman is not Jewish.
