Iran’s Supreme Leader had decided he’s had enough and will be starting no investigations at all. Khamenei announced this morning at Tehran University that the demonstrations are illegal and that the election was fair.
I am afraid this may be the entirely wrong move to make. Especially after announcing he would investigate the election, this announcement is basically an admission of wrongdoing. Its also the most obvious move for an authoritarian government which relies on the cult of personality and the perceived strength of the leadership.
I think that this might be blood in the water for protesters who have gotten used to their voice being heard by the world.
