Try again, fool. The pictures show them in plain view, on the streets during the protests and inside Mousavi's headquarters after it was seized by the regime's forces. Your denials only make you look dumber and dumber. As said before, they are not used as the first line of attack. They are back-ups for when things get out of hand, because the regime can't rely on Iranian troops to use brutal force against civilians indiscriminately. To everyone else: There is really no point in trying to reason with such brainwashed zombies. They only ask for proof as long as they think no hard evidence is available. Once the evidence is offered they immediately dismiss it as fake. The best way to deal with them is to not give them room to spread their lies and misinformation.
