scott olson. olson had served two tours of duty in iraq during which he turned against the war and began speaking out. other protesters, including jesse palmer, are nearby when police decide to act. >> we were in the intersection, and it was actually fairly calm, and then all of a sudden the explosions went off and the tear gas was kind of all around us. >> protester ernest doty, a local artist, is there too. >> kind of out of nowhere the whole mood changed. it got very violent very quickly and just got really chaotic. >> in addition to tear gas, police also fired bean bag projectiles and flash-bang grenades, both considered non-lethal crowd control measures. >> then people, of course, start panicking, and then to the right of me i saw scott olson get hit.
