A challenge for Egypt's military justice system

This morning's New York Times has this article about the emergence of a disturbing video of Egyptian soldiers shooting unarmed men in the Sinai Peninsula. The question is whether this will go down as merely an instance of impunity or spark serious military justice proceedings. It already stands as yet another milestone in the growing series of incidents in which criminal conduct by military personnel of various countries (the Blackman case in the UK, the U.S.'s urinating marines immediately come to mind) has become widely known because of video technology available on inexpensive and ubiquitous bodycams and smartphones.
