About the gaz used in Moscou
After having watched to an BBC-show, I found very interesting informations about those gazes.
First, Fentanyl an Sofentanyl isn't intensive enough to clear 1000 people on an area of 13500 m³.
For Fentanyl their must been introduced an quantity of 19,2 Kg (of gaz!!!) impossible!!!
Only the Fentanyl-derivate Carfentanyl has this capacity.
After calculating an average value; to shut-down the tchechen-hostage takers their had been introduced an value of apprx.: 640gr. (of gaz) Possible!
But the russians had only an dying rate of under 15% (129 from 1000) that were impossible with carfentanyl; because carfentanyl causes to stops respiration;
so they had developed an new gaz witch isn't cleared up by european or american developers!
Last year their was an inovation on this sector;
devolopers found an method to react anti-respirating of the concerned persons.
carfentanyl in combination with WNU-8.
Personally I think Russian Special Forces had done the right thing, because the risk that they blew-up the whole 1000 hostages was too High! And they must done introduce the gaz in a high quantity because the tchechen rebels are trained, and had the highest resistance in the whole room!
Other tag: Not the gaz did took the live of 129people,
but it was the position how they fell asleep, they were killed because their neck had felt backwards, making the respirations badly and the blood circulation badly too!
Russian Special Forces had to wait until to be sure that the tchechen were asleept (it took 1 hour!)
The anti-opiate Naloxan couldn't be introduce enough because most of the hostages were already dead!
German specialists hadn't found carfentanyl in the blood and urin, because the new opiate-narcotic gaz of russian SF
were a new chemical (perhaps carfentanyl with WNU-8)
But 129 died, still to much!
