Today's events show that the crowds were willing to test Khameini's and the regime's will. Question is, will they be willing to go out again knowing that the regime is likely to try to keep upping the pressure?

If they do show again the regime will be forced to decide between going all out and turning up the violence or blinking. If the regime does want to turn up the violence, it has to consider just how much stomach its rank and file have for killing their countrymen. Will the police commander who said today, "I have a wife and kids. Please go home so we don't have to beat you," be willing to keep increasing the violence?
