Revolution in Iran?

I'm not sure what I think about all of this, but the people of Iran are protesting, marching in the streets of Tehran. More from Breitbart:

Hundreds of thousands of protesters wearing black and carrying candles filled the streets of Tehran again Thursday, joining opposition leader Mir Hossein Mousavi to mourn demonstrators killed in clashes over Iran's disputed election.

The massive protest openly defied orders from Iran's supreme leader, despite a government attempt to placate Mousavi and his supporters by inviting the reformist, and two other candidates who ran against hard-line President Mahmoud Ahmadinejad, to a meeting with the country's main electoral authority.

Many in the huge crowd carried black candles and lit them as night fell. Others wore green wristbands and carried flowers in mourning as they filed into Imam Khomenei Square, a large plaza in the heart of the capital named for the founder of the Islamic Revolution, witnesses said.

It all started after their country's presidential election. Apparently, they believed it was rigged. Sound familiar?
