You can tell by the fact that the policemen are still alive at the end of the video.
But the Mob could be starting to wake up. The murder of Neda is, as Time notes, a potential triggering event to an increasing cycle of death, mourning, repression, and more death; and that will wake the Mob. And when it does, neither the police nor the swaggering brownshirts supporting the Iranian regime will survive their next encounter. At which point the Iranian military - which can survive the Mob - will have to decide whether or not they want to shoot down a lot of people.
It is my sincere, honest, and earnest suggestion to the current rulers of Iran that they spare their country a lot of grief and anguish and simply quit power now. I expect that they won't, but I could be wrong.
