Last time, during the Russian movie theatre standoff, the entire building was gassed with a sleeping gas. The theory was good, but in practice, many of the old and young died from doses that were too much for fragile bodies.
These Chechnyan animals probably realized that the Russian Security forces would not try the "sleeping gas" technique in a building full of children. A dose high enough to knock then out, would surely take the lives of most of the children.
Fox News reporting that there are still children being held hostage in the school.
Apparently the terrorists knocked out all the windows to prevent a reuse of the gassing tactic.
These laughing hyena, slavering, cult worshiping butchers of Islam need our quick 1000 fold vengeance.
