"Annette Spicuzza, the U.C. Davis police chief, told The Sacramento Bee that the officers used pepper spray on Friday because the police were surrounded by students. 'There was no way out of that circle,' she told the newspaper. 'They were cutting the officers off from their support. It's a very volatile situation.' The videos show officers "freely moving about" and students behaving peacefully. The university reported no instances of violence by any protesters." : from "U.C. Davis to Investigate Use of Pepper Spray at Protest" by Brian Stelter, The New York Times, 20 November 2011
"In New York, many of these reports involve allegations of excessive force used by NYPD officers against OWS protestors. These allegations, many of which are supported by extensive documentation on video and in press accounts, involve numerous incidents over the course of the several weeks... OWS in New York is only one of several protests around the country where similar tactics have been reported. Demonstrators participating in Occupy Oakland, Occupy Berkeley, Occupy Seattle, Occupy U.C. Davis, Occupy D.C., Occupy Los Angeles and Occupy Philadelphia have all made public videos and recordings showing police using significant and unwarranted force in making arrests." Sonmez, F.
