CNN reports on the use of tear gas by the Oakland Police Department on Occupy Oakland protesters.

 

Authorities made a series of arrests at Occupy Wall Street protests in California and Georgia on Tuesday and Wednesday, with clashes in one city that involved tear gas being used on demonstrators.
Police said they fired the tear gas on protesters in Oakland, California, after the crowd threw paint and other objects at officers. Among the injured in the clash was a two-time Iraq war veteran, Scott Olsen, who sustained a skull fracture after allegedly being shot in the head with a police projectile, according to Iraq Veterans Against the War.

New York Daily News has video of an October 14th incident in which an NYPD officer punched an Occupy Wall Street protester in the face.
