Oakland police have posted on their website dozens of audio and video files and dispatch records relating to the Occupy protests in October and November.

"The Oakland Police Department is dedicated to policing in a manner that is both constitutional and ethical," reads the notice on the site. "During the Occupy Oakland operations of October and November 2011, our goal was to facilitate free speech and peaceful demonstrations. This web page has been created to share media recordings (audio and visual) of events as they happened."

Visitors can download raw recordings taken from the radio channels used by Oakland police during protests on Oct. 25 and Nov. 2 and 3, and read transcripts of police radio communications and calls received, among other communications.

Several protesters said officers who responded used excessive force to quell the demonstrations, including firing tear gas on crowds and using flash grenades and nonlethal projectiles.

The department is conducting reviews into the police response.

"This is a work in progress," a note on the site says. "Material is being uploaded as quickly as possible. Eventually, documentation will be accessible for all four operations. Keep checking back!"
