Not proven lame brain, he tossed the tear gas after he was in the theater. The only one with NO FACTS and a LOAD of BS is You Jayne. I bet you never even owned a water pistol did you. I bet you only use dull knives because your afraid you'll cut yourself. Why do they left mentally deficient people like Jayne walk the streets: They are dangerous even to themselves.
Tear gas is NOT pleasant, but you can STILL see and shoot in a cloud of it; The tear gas exercises in the Army is just to train you in case of more lethal gases as used in WW1.
