We cannot understand change in Iran simply through the prism of replacing one group of power hungry tyrants with yet another group of power hungry tyrants whether we call it a Islamic republic, a secular republic, monarchy or whatever system of government. The point is that we have to fundamentally change the roots of power and legitimacy. Power is not a license to kill. Power is a responsibility that is owed by leaders to ensure the rights of each and every Iranian citizen…[Audience Applause] and until.. those that trample human rights under their feet with such violence are not brought to justice, we will never have the future that we all want to build. We will never have a culture in Iran which is based on the dignity of all human beings. Getting to this stage is going to be a difficult task.
