(Portland, OR)  --  Police say they arrested seven people during yesterday's anti-hate rallies in downtown Portland.  Police say two officers were injured when demonstrators threw objects and smoke bombs at them.  One officer was hit in the face with a projectile, while the other was hit by a slingshot.  Officials say that at one point, anti-hate demonstrators got into a shouting match with members of the right-wing "Patriot Prayer" group, before the Patriot Prayer demonstration moved to another location.
