Where is humanity?

I have just seen some videos of today's protest. The heavily armed police forces stopped the people from demonstrating by using water canons and tear gas, and beating them unbelievably brutally. They beat to kill, not even to stop them! Just to kill!! I have just watched a video showing a young woman being shot in chest by Basij paramilitary, I am shocked, wordless. Who can do it? For what? She died just for watching demonstrations or maybe taking part in it! Is it the way that a government treat its people, specially a government that calls itself Islamic? Is that Islam? Is that a constitutional republic?Barbarians do what they can do to keep the power and control a whole country with bloody hands. Where is humanity? What are they doing? I heard many people have been died and much more injured today!! History shows that Iranians will not forgive the people who handle them with guns and brutality. We will put you in your place. I am emotional, but they are killing us, they are shooting us. This is our country. Where is the so called free world??! We need support.
