Some sort of nerve gass made people tremble like hell.
Nerve gas is a lethal weapon. It was used by Saddam against Kurds, and most of the exposed to it did not just tremble, they died. I do not know anything about the new gas, but if it causes only temporary disruption of muscular functions, then this is a non-lethal weapon intended to put end to mass disorders, just like well-known tear gas. And it has nothing in common with Zyclon, Sarin, Soman, VX, Yperite and other WMDs.
Usage of non-lethal weapons is humane since it can substitute usage of the lethal ones.
Some people get strongly disappointed when the Jews defend themselves against murderers, instead of acting like sheep in the butchery.
About BBC. Three days prior to being drafted to the "Defensive Shield" operation in late March 2002, on the peak of terror attacks on the Israeli civilians, I watched on this channel a "documentary" openly glorifying the terrorists. This was the last time in my life that I chose this channel of the cable TV (I was unable to unsubscribe, since BBC was a part of the so called minimum package). I strongly respect the United Kingdom and its people, but it seems to me that BBC is occupied by the leftist replicas of "lord" Haw Haw.
