Haruna, 

This piece was being written when the butchering  of these young and innocent students was emerging on the List.

Please read Yus's posting properly. He neither used the word "exonerated" nor implied to it for once. What Yus is saying is that the emphasis of blame should be more on those who murdered Ebrima Barry than the teacher. There is no legal system that I know of, where the teacher could be held solely accountable for the death of Barry. You said the teacher is "culpable" Yes, that maybe true, but culpability is not always premeditation. It is a common thing for one to be "culpable" of something that he is innocent of. The news of the massacre of these poor is what Yusupha Jow is talking about. Are we now going to blame what led to the demonstration or people who pulled the trigger? 

The fact is YAYA MUST GO!!! AND GO HE WILL.
