You have to sign in to watch it (it's pretty graphic) but this is a video that was taken 2 days ago, of a woman named Neda that was shot to death by Iranian police. In the video it shows her on the ground, shot through the lungs, blood coming out of her mouth and nose, blah blah... it's pretty disturbing, and is well worth taking the two minutes to create an account on youtube for it.

Can someone please tell me what the *^(# is going on over there? I know there has been protests and demonstrations (such as the one above), and that there was something about rigged (or supposed rigged) elections, but can someone tell me what is basically going on over there and why horrible things like this are happening? I hear so many different things I don't know what to believe, anybody keep up with politics and the like?
