One of the big questions was where Moussavi would come down, seemingly having a great deal of weight on his shoulders.  State TV there has already reported that he will be held accountable for violence.  Moussavi was left to decide whether he wanted to keep going or back down in order to save lives.

And I guess we get our answer on that now, in a speech he is giving as I type this (via Sully):

11.40 am. Mousavi: I Am Ready For Death.

Be nice to America. Or we'll bring democracy to your country.
