If the latter is really true (and not only seemingly so, let's say, because the weather conditions were such that it was impossible to move in a different manner), that really leaves only two options in my view. Someone either forced them to leave and kept them under gunpoint, or there was some sort of group lunacy taking place.
It should be completely clear, even superabundantly clear, that the nine students were forced out from their tent at gunpoint, because the attackers wanted them to freeze to death. If there had not been a relatively mild temperature of around -15C during the early evening, this would have been the perfect killing mission.
The attackers must have cut the tent, either from the inside or the outside. There is nothing to indicate that the nine left the tent through the cuts in the tent.
The injuries sustained by the students are all consistent with an attack by special forces trained in close combat.
These nine unfortunates simply were at the wrong place at the wrong time.
Most telling of all is the obvious cover-ups by the Russian government. Every knowledgeable person knew and knows that there was no avalanche in the area. Yet the Russian authorities insist that they all died from an avalanche. What does that tell us?
The Russian authorities knew very well what happened. Very, very well.
