40mm tear gas launcherMarine Says Oakland Used Crowd Control Methods That Are Prohibited In War ZonesRobert Johnson and Linette Lopez | Oct. 28, 2011, 8:28 AM
As the events that led to Oakland protester Scott Olsen's head injury continue to unfold and investigations begin, we thought it important to offer some perspective.
This comment is from a former Marine with special operations in crowd control.
He points out that shooting canisters such as those that likely hit Scott Olsen is prohibited under rules of engagements in Iraq and Afghanistan. Regardless of any political position on the Occupy protests, these are some Interesting insights:
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!!
