Bombing of Aleppo University: another opinion

A comrade sent me this but he does not want to be identified because he is terrified of Syrian "revolution" groupies:
" As`ad, your source "Saf" is not trustworthy nor are his testimonies. I am appalled at the number of people in Aleppo who "saw" the bombs being dropped from the plane. I lived most of my life under Israeli raids and I never saw the bombs dropping from the planes. How come nobody in the international media gave credence to all those eyewitness testimonies? I mean, really, I would perhaps have understood if the opposition claimed that the regime bombed the place by mistake, but their explanation makes clear that they are propagandists with no interest in the truth. ".
