I don't know how to argue the point and I'll repeat, I don't rule out outsiders , I would rather rule out natural possibilities, then consider outsiders. As you suggest, it's an odd way to kill people.
What I clearly stated, is that to let the cold to the grisly job is a very intelligent way of killing people: To make it look like an accident in the cold. Almost any other way of killing them would have been too obviously a murder. This method would have been a complete success, if the temperature had been low enough to kill the nine without further intervention. To chase the victims out of their tent and into the cold - what method of killing can be more cruelly intelligent, if the order from above was to make the deaths look like an accident?
Why would the investigators be instructed to close the investigation down prematurely with the conclusion that it was an accident, unless it was something entirely different?
The injuries tell their tale, and they can only be explained by lethal attack by other humans.
I don't entirely disagree , however, I need or want to challenge your thoughts.
Outsiders could have made the dp9 look like they were digging the trench for the tent as per the alleged last photo. The cold had already worked on several members of the group if we assume outsiders were trying to kill them in that way, that way being, death by hypothermia.
There is then no point in breaking skulls or breaking ribs? Just strangle them , there will be less evidence? Marks on the neck will not show when there is nothing but a skeleton, but broken ribs and skull fractures will?
The investigators closed it because they hadn't a clue? There were many tourist trips that ended with people losing their lives. An embarrassment all round perhaps?
The injuries say something happened for sure. We must be 100 % that those injuries ( broken ribs) could not happen in the environment. I will argue in the first hand that the ravine 4 were found under 3-4 meters of snow. I have to ask the question,, can we be certain that a mass of snow , falling on top of bodies cause these injuries. I do not have the resources to know for sure, but we have ather reports from around the world that show that broken bones from snow collapse, land slip are posable. That fact, in my opinion cannot be ignored. To me, it's the first angle we look at.
Others have put explanations forward. The potential of a tree causing the injuries for example.
If you wish to say there was a bunch of trained guys doing Kung Fu, without their pyjamas on but in heavy , 1950s clothing , I can't argue the fact.
