Just talked to a pro-Mousavi contact in Tehran. He had several points I am going to list here:
1- There are two group of protesters a) Tech savvy angry youths (14-21) who are very angry with the regime looking for headaches and want to fight the regime to death example of their action seen in Vanak Sq in Tehran. One 14 yr old was shot to death in that area. b) Adults and mature people of all walks of life who do not resort to violence and don't like confrontations (example of which the peaceful protest in front of regime TV bldg on Tuesday).
2- The state of affairs in Tehran is like an active volcano which happens to be out of control. Regime has no apparent control over the people and their behavior or reactions. People are agitated and example is when one road is blocked, people pour to protest sites from multiple routes that can not be controlled by police or militia.
3- Basiji militants seek to provoke people intentionally. They have no problem shooting at the crowds or gunning down their opponents.
4- Regular police forces have been very friendly in many cases. Also they have in some instances detained some of Ahmadinejad supporters for trouble making.
5- The rage among people has not gone down. It has gone up very much. Though people don't want to be violent if the regime is not violent. The rising death toll is intensifying the anger among the people. That has added to their hatred of the system.
6- Mousavi has vowed not to let people down. And my friends believe he won't let his supporters down. My friend adds if Mousavi does not let people down, his 1980s crimes can be forgiven.
7- The momentum is in favor of the Iranians. People prefer not to resort to violence as much as possible. One of the signs carried by my friend read: "Support Mousavi, No To Violence!"
These are several points mentioned by my close friend in Tehran via phone. Though the connection is bad and it was disrupted twice (hopefully his line is not tapped).
On a side note on angry teenagers: My friend said these young guys and girls ALWAYS talk about how to defeat anti-riot police. Always talk about how to defeat the regime on the internet. Always discuss the ways to learn how to combat in street fights. Always discuss how to hack regime websites. It can not be denied that Iran is in a pre-revolutionary mode now and anything is possible. A little bit of pressure from the outside world can tip this thing in favor of the liberty and humanity.
That's all for now! I'll keep you posted..... (really need to get some sleep and do some errands)
