Before gas goes into a crowd shield bearers have to be making no progress moving a crowd or crowd must be assaulting the line. Not with sticks and stones but a no bullshit assault. 3 warnings must be given to the crowd in a manner they can hear that force is about to be used. Shield bearers take a knee and CS gas is released in grenade form first to fog out your lines because you have gas masks. You then kick the canisters along in front of your lines. Projectile gas is not used except for longer ranged engagement or trying to steer the crowd ( by steering a crowd I mean firing gas to block a street off ). You also have shotguns with beanbags and various less than lethal rounds for your launchers. These are the rules for a WARZONE!!

How did a cop who is supposed to have training on his weapon system accidentally SHOOT someone in the head with a 40mm gas canister? Simple. He was aiming at him.

Redditor ‘SawOnPoint’, former Marine with special operations training in riot control regarding the Oakland PD and their ‘assistants’ from other departments’ totally unacceptable and unprofessional crowd control methods. (via bstriddy)
