A reader explains:
I saw your post on Hajjarian's arrest. I was in fact wondering with a few friends what has come of him. This is wikipedia page on him, to give you the context.
He is a very very brave man who blew the whistle on chain-murders of the dissidents and intellectuals by the ministry of Information and paid a very heavy price for it. This is a very big deal. Also Abtahi is a reform minded clergy who was Khatami's chief of staff and deputy.
These guys are going after everybody.
