iranintl, yah that's an instant rejection.
There are zero verified sources of any mass killings by the Iranian government. In fact all evidence points to Mossad agents committing the mass killings of Iranian government officials as caught on video, including the wrestler that was just executed for killing a police officer with a machete, on video.
Any links to the on video bit? Most stuff on the internet seems to say he didn't do anything except protest.
