Federal investigators have issued new subpoenas to the Oakland Police Department as part of an escalating federal probe following FBI raids. The subpoenas demand the department turn over records, which has been described as a complicated task by Stanford Law Professor Robert Weisberg. Weisberg commented on the situation for KQED in 'Oakland Ordered to Turn Over Records as Federal Probe Escalates After FBI Raids.' The investigation aims to determine if any victims have filed complaints related to those under investigation, rather than uncovering wrongdoing by the police department itself.
