After three notably violent crackdowns on protesters in as many weeks, Oakland Police Department officials have refused a request by the ACLU of Northern California to release police reports documenting their use of force as required by law.
“We saw events that we found extremely troubling, and which violated provisions of Oakland’s own crowd control policy,” Linda Lye, a staff attorney with ACLU of Northern California told AlterNet.
After recent police actions in Oakland gained national attention, “there was a lot of lip service paid to transparency and accountability and the public’s interest in monitoring the situation,” she said. “But then OPD proceeded to say that it was invoking one of the statutory exceptions to the Public Records Act for the vast majority of our requests.”
