While protests that rocked the streets of Tehran for days have largely died down, the quiet is not a sign of acceptance.
"A majority of the people — including me — do not accept its political legitimacy," Mousavi said on Wednesday. "There's a danger ahead. A ruling system which relied on people's trust for 30 years cannot replace this trust with security forces overnight."
