It's an older story now, but it still pisses me off just the same. The girl who was killed became a sort of symbol for the entire protest/revolution.

Here's an article complete with a youtube video of someone catching the entire thing on tape (http://gawker.com/5299414/neda-the-face-of-a-revolution)

Wiki page (http://en.wikipedia.org/wiki/Death_of_Neda_Agha-Soltan) too, since it really was pretty big.
