public face

ここのpublic faceは辞書にもない表現ですが、おそらくは9/11以降、国際指名手配となりあまねく世間に知れ渡ったテロリストの「おなじみの顔」という意味でしょうか？（UG）

(CNN) -- Abu Yahya al-Libi, the No. 2 man in al Qaeda and a longtime public face of the terrorist network, is dead, White House spokesman Jay Carney said Tuesday.
Al-Libi's death was "another serious blow to core al Qaeda," said Carney. "His death is part of the degradation taking place in core al Qaeda in the last several years," Carney said.
Earlier Tuesday, U.S. officials said that al-Libi was killed Monday by a CIA drone strike in Pakistan.
Al-Libi's death marks one of the most significant blows to al Qaeda since the U.S. military killed Osama bin Laden in a daring nighttime raid in Pakistan a year ago.
