1) You appear to be unfamiliar with the game "sardines", or Times Square. People don't take up much space, especially when standing up. There are 27,878,400 Square Feet in a square mile. Each square foot can hold a person, standing up. That means in a square mile, you can fit up to 27 million people. (not pleasantly or comfortably, but it can be done.)

2) Police have guns and fire hoses. Any of these alone is enough to control a crowd several times the size of the police force, especially the fire hoses.

3) Amanjeed (mispelled i know) is not known for employing logic. Indeed, the primary reason given by many of Mousavi's supporters was that Amanijeed was too capricious and arbitrary in his decision-making. And when you control all of the important offices and agencies (i.e., the state police and military), politics is just for show.

4) This is incorrect; the Ayatollah did not approve of the election; that is why they have launched an investigation into irregularities.

You clearly didn't put much thought into your own claims.
