It was Iran's day of destiny and day of courage. A million of its people marched from Engelob Square to Azadi Square – from the Square of Revolution to the Square of Freedom – beneath the eyes of Tehran's brutal riot police. The crowds were singing and shouting and laughing and abusing their "President" as "dust".

Mirhossein Mousavi was among them, riding atop a car amid the exhaust smoke and heat, unsmiling, stunned, unaware that so epic a demonstration could blossom amid the hopelessness of Iran's post-election bloodshed. He may have officially lost last Friday's election, but yesterday was his electoral victory parade through the streets of his capital. It ended, inevitably, in gunfire and blood.
