It is proof that they are free, at least to a certain degree - or they woudn't be marching.
In as much as (1)the Mullahs don't give a damn what the majority of the people in Iran want and (2)the Mullahs have rigged the "election" system so that no one they don't want can even consider being a candidate for anything, (3) the protests, as far the Mullahs are concerned is simply "bread and circus" ("let the little darlings blow off steam, so they won't blow off our heads").
You can call that "freedom", but at least the protestors, unlike you, know it is as false as the sham elections.
I bet there were a lot of "free" Japanese marching to the bushido drum. The people that run the country all have very short hair and nappy beards. These are known as the macho men of Iran and they want action, big time action. They want us to go up in flames, preferably at each others throats after they set up the chain of events.
I wouldn't say that. It said they had police and vigilantes present. The Chinese students protested once too. Didn't work out so well.
