Assefa,

Don't twist the matter. Whatever Tesfaye Birru does is watched by Haile Assegdie, Kassu Ilala and Getachew Belay, who in turn are installed and controlled by the PM. If there is corruption at the Manager's level, it is logical to believe there is also the same all the way up to the PM level. The major difference in their role is that the system is so designed that the PM can throw these guys to prison whenever he wants to do so, whereas the reverse is impossible. The only way out for these guys is to flee earlier than the touch of the button or pray for the mercy of their chief.
