So... it's been three months. Do we know who shot whom?
No, indeed! "Tabo says courts can make exceptions under certain circumstances and in those cases, gag orders don’t violate The First Amendment. '[But] the standard is supposed to be quite high,' she says."
Nine people died at that shootout. Who shot them? An attorney out of Vegas claims, allegedly based on talks with the bikers, that the police killed them all. This would be an easy charge to rebut by releasing physical evidence. For example, were these gunshot wounds from handguns, or were they from rifles? That's very easy to determine in an autopsy.
Also: "All but two of the 177 have been released, and no one has been formally charged." No one? That's kind of amazing. Almost two hundred people were arrested, and no charges have been filed?
