The results of investigations into tactics used by campus police during Occupy protests at the University of California, Berkeley, and the University of California, Davis, will not be released until later this month or early next month, missing deadlines set by university officials.

The Berkeley report, which was due January 31, will not be issued until at least the end of February or early March, and the Davis report may be released on February 21.

Berkeley Police Review Board chair and law professor Jesse H. Choper cited lack of "meaningful" student input as the primary reason for the delay in a letter on Monday to Berkeley Chancellor Robert J. Birgeneau. He noted that students were away on winter break during most of December and January.

Chancellor Birgeneau launched the investigation after videos posted online showed UC Berkeley police using batons to breaking up a circle of protesters during an Occupy protest on November 9.

Less than two weeks later, on Nov. 18, a UC Davis police officer pepper-sprayed a group of Occupy protesters who were sitting on the ground with their arms linked. A report on that incident was due at the end of December.

But last month Cruz Reynoso, who is leading the investigation at UC Davis, sent a letter to Mark Yudof, president of the University of California, informing him that the report's findings would not be released until Feb. 21.

Reynoso wrote that the delays resulted from difficulties in negotiating access to “non subject” officers with the Federated University Police Officer’s Association. The issues were resolved and Kroll, a private security firm led by former Los Angeles police chief William J. Bratton, began conducting interviews with the officers around January 20.

The report could be delayed further if Reynoso decides he needs more time, according to Davis spokeswoman Claudia Morain.

University of California spokeswoman Lynn Tierney said a campuswide review of police conduct is still expected to be released in early March. However, that review could also be delayed if the officials in charge, UC General Counsel Charles Robinson and Berkeley Law Dean Christopher Edley Jr., decide to use details from the Reynoso report to inform their recommendations.
