by ‘projectiles’ they mean rubber bullets

ST. PAUL, Minnesota (CNN) — St. Paul police fired chemical agents and projectiles into a large crowd of protesters outside the Republican National Convention on Tuesday night. Witnesses said the protesters marched from the grounds of the state Capitol after a concert there ended abruptly. The protesters were noisy but peaceful as they approached the convention. Once they arrived, a police officer read an order to disperse, CNN reporters on the scene said. But almost immediately, officers along the exit route opened fire with gas and projectiles. In one instance, a CNN producer said, an officer stepped out of line to hit a young woman with pepper spray as she ran for the exit. Police said officers were trying to scatter protesters who they said were trying to get past security fences. Police told the AP that about 2,000 people participated in the anti-poverty march, which lasted about three hours. Other officers used gas and pepper spray in the path of those attempting to comply with the disperse order, forcing some to stop in their tracks, a CNN crew reported.
