Karpy, I've never heard of CS being banned by anyone of any country by any treaty. You're probably thinking of other gases. Like the lethal ones and shit.

I like how you spout reading like you know what you're talking about. CS gas is what they use in military and police training. We purposely get gassed. It's not nearly as bad as your reading makes it out to be.
Especially in open, outside spaces where people are free to move and leave- which is the point anyways. You would have to be deliberately keeping yourself in the gas cloud/right next to the canister to for it to start to be overbearing, even for those more sensitive to it. (mind you, I've been purposely exposed to high doses of it in small enclosed rooms and was not let out until after a certain time, multiple times in a row) It is actually quite easy to wash off in a shower. It burns, the natural and correct response is to get away. And getting sweat, water on the affected area does initiate the burning sensation again. Which is more akin to a mild sunburn and really doesn't last that long if you were smart enough to get out of the way.
Getting hit in the head by a canister. Is this really a huge concern? Really? What if you tripped and fell and got trampled by the rest of the crowd? herp derp.
What moron still brings children to the protest/riot lines at night after all this time? This shouldn't be a thing.
I keep hearing this thing about innocent civilians and not enough of how there some civilians who aren't so innocent mixed among them in the crowds. Or how the crowds, like in the video I last linked are deliberately disobeying reasonable commands and control lines.
"It's not a warzone." But you have a large group of people who are potentially armed with guns and/or knives. Expect rabbits but prepare for bear. You guys see their gear, but they have their weapons, and stuff that holds the rest of their nonlethal equipment, like handcuffs and zip ties and radios and tools and you get your panties in a bunch about being militarized. Helmets are for safety. Gas masks are so the police can stand in place and enforce their lines if/when people toss the canisters back at them. If you think they look all that rough and tough, it's because you don't have a trained eyed for these things. It's people psyching themselves out and panicking.
Why are people afraid of armored vehicles? It means if people start shooting, the cops will be safe inside. Do you expect them to run people over? I don't see the mounted machine gun at the top of those vehicles that the military would have.
CS gas is still better than getting shot by rubber bullets and shit, and keeps the cops out at a safe distance and out of reach of the crowds. I mean, I suppose some of you people would prefer a riot shield line with batons and mace and side arms and direct contact and much higher potential for injury for law enforcement and protesters alike. Or go back to hosing people down from fire hydrants.
I see total panic and a lack of informed perspective.
And as far as Godot is concerned, his information is second via myself and at least one mutual friend who is in the airforce.
