A CNN article said today, "...police arrested 34 in Colorado Springs, Colorado, on failure to disperse and other charges. Police used pepper spray and tear gas to break up the group. After one person threw a tear gas canister back toward the officers, police fired rubber bullets at him and used a stun gun."
The Colorado Springs Gazette says that the police ordered protesters to disperse because they temporarily blocked an intersection. When the protesters did not disperse, the police became violent.
