Russian prosecutors investigating last years' deadly siege in Beslan, North Ossetia and the even-more-deadly attempt to lift it have determined that officials on the scene and in Moscow made no (that is, zero) mistakes.
Let's take a moment to remember that more than 330 people lost their lives in this series of events, many of them little kids. There's a great deal of debate regarding the timing of the raid that was supposed to lift the siege: Did government forces storm the school after explosives placed by the Chechan terrorists started to detonate? Or did the explosions start after the raid began?
The victims' relatives are already good and mad at the Putin government. This won't help matters.
