1- Normally people wear warm clothing before they go to high altitude areas with snow , I am sure the victims were not properly dressed
2- The authorities which monitor weather should have send out alerts to tell people to not go a region where roads will be blocked - did not happened
3- After heavy snow , there was no mechanism to track blocked vehicles in remote area
4- Did we not have any rescue helicopter to send out (perhaps no one knew who to call for help), when we have some mountain climbers stuck on Mountain sure there is a process which is followed to rescue , did we not have a helicopter in region to fly over to see who is stuck ???? or Not ???
So failure on multiple points
Hotels/Restaurants normally charge certain profit margin they perhaps did not understood how many people would get stuck , could be case of misunderstanding or plain greed
It is not job for Army to send in soldiers to go remove snow
This is job for Local City officials to ensure they have plans and process to clean up roads from snow
