Special to the Vanguard

On Thursday, 36 victims of police violence, police accountability experts and former prosecutors sent a letter to California Attorney General Rob Bonta arguing that his office’s charging of Los Angeles Assistant District Attorney Diana Teran could have dangerous ramifications for the oversight of law enforcement across the state.

The letter argues, “the Los Angeles District Attorney’s Office has a duty to hold officers accountable if they break the law and to comply with its constitutional Brady obligations to disclose officers with histories of misconduct to the defense.”

Teran, the letter explains, “was hired to oversee this law enforcement accountability work because of her decades of experience in prosecution and police oversight.”  However, now “she has been accused of acquiring documents the prosecution is entitled to request but is charged with accessing them through the wrong channel.”

The documents in question, the letter explains, were used in her role within the District Attorney’s Office to comply with discovery and to ensure the fair administration of justice for everyone.

The DA’s office, the group argues, “not only should have access to records about crimes or other misconduct committed by law enforcement, but they must have these records to fulfill their constitutional obligations.”

In fact, they add, many police misconduct records are now accessible not just for prosecutors but also for the public at large.

“Police misconduct should not be kept in the shadows. It’s very troubling that a prosecutor could be indicted for working towards such transparency and accountability,” said Erwin Chemerinsky, Dean of the UC Berkeley School of Law and a signatory to the letter.

“Ms. Teran’s work for the DA’s Office overseeing a non-public, internal DA database of police misconduct findings enabled prosecutors to fulfill their constitutional obligations in criminal cases, and such conduct should be applauded, not prosecuted. The charges brought against Ms. Teran are against the public interest in ensuring compliance by prosecutors with their constitutional obligations,” said former Los Angeles County District Attorney Gil Garcetti.

“Law enforcement departments in Los Angeles and across California are desperately in need of adequate oversight. Prosecuting a public servant in order to shield police misconduct from the very agencies tasked with holding law enforcement accountable is a dangerous and deeply troublesome approach. The effect of this will be chilling, as others doing this important work will have to fear that carrying out the requirements of their jobs will imperil their careers and put them at risk of imprisonment,” said Cristine Soto Deberry, Executive Director of the Prosecutors Alliance, the organizer of the letter.

Signatories include former Los Angeles District Attorneys Gil Garcetti and Ira Reiner; former San Francisco District Attorney Chesa Boudin; Valerie Castile, mother of Philando Castile; Tahir Duckett, Executive Director at the Georgetown Law Center for Innovations in Community Safety; Ellen Yaroshefsky, Howard Lichtenstein Distinguished Professor of Legal Ethics at Hofstra Law School; and Michael Gennaco, Principal at OIR Group, which provides independent police oversight and review, and former federal prosecutor and head of the Civil Rights Division for the Central District of California.

Full letter: Prosecution of Diana Teran, Assistant District Attorney in Los Angeles, and Appropriate Police Oversight

Dear Attorney General Bonta,

We are a group of former prosecutors, legal scholars, policing experts, and relatives of people who have been victims of police violence. We are writing to express our concern at the recent charges your office filed against Los Angeles Assistant District Attorney Diana Teran, and the chilling effect we believe this will have on policies and programs intended to ensure transparency, promote public trust and confidence in law enforcement agencies, and enable agency compliance with constitutional obligations. Ms. Teran is a long-time prosecutor with experience in police oversight, and she was hired by the Los Angeles District Attorney’s Office (LADA) to oversee the LADA’s maintenance of an internal, non-public database of cases involving findings of police misconduct. The press release from your office, read in conjunction with the complaint available on your website, suggests that Ms. Teran is being prosecuted for uploading data reflecting official findings of officer misconduct that you believe was taken from an LASD database into an LADA Brady database. The LADA Brady database is not public, and whether the facts you allege are true or not, we believe you should exercise your prosecutorial discretion to dismiss the charges in the public interest.

Ms. Teran spent over a decade as a prosecutor in the Los Angeles District Attorney’s Office beginning in the 1980s, and well over a decade in police oversight roles with the Los Angeles County Office of Independent Review, the Los Angeles Sheriff’s Department, the Inspector General’s Office, and the Los Angeles County Public Defender’s Office, before returning to the District Attorney’s Office where she served as Assistant District Attorney of Ethics and Integrity Operations. After a 30-year career in prosecution and law enforcement oversight, Ms. Teran is now accused by your office of improperly “using” LASD data to maintain an LADA internal database. The prosecution sends exactly the wrong message to the public and is against the public interest you were elected to serve.

All law enforcement entities should have access to records memorializing official findings of officer misconduct and crime. Such data is supposed to be public under Senate Bill 1421, but we will not speak to the merits of the charges, other than to share our concern that they are defective on their face because the data allegedly “used” appears to be public data and, separately, because Ms. Teran was acting in her official capacity when doing the things you allege she did. Instead, we speak only to the wisdom of your decision to exercise your prosecutorial judgment to file the selected charges because we believe the charges filed are contrary to the public interest you were elected to serve.

We believe the charges you filed will erode public trust and confidence in law enforcement efforts and will reduce transparency. Efforts by the LADA to maintain a Brady database are intended to promote public trust, increase transparency, and ensure there are processes in place to comply with constitutional obligations. Ms. Teran did not publicly disclose any data or records, even though under SB 1421 they were already public if they memorialized findings of police use of force, sexual assault or acts of dishonesty Instead, she added data to a private law enforcement database, which your office should applaud, not prosecute. Prosecuting Ms. Teran for “using” relevant data in her official capacity in the manner alleged sends the wrong public message: that protecting law enforcement officers who have committed acts found to be disclosable misconduct is more important than complying with constitutional obligations in the pursuit of justice.

We strongly urge you to reconsider pursuit of this case, whether or not you believe you can sustain the allegations at trial. We believe it is in the public interest to dismiss the charges to emphasize your belief that law enforcement agencies should share data necessary to comply with Brady, especially when both agencies operate in the same County and have overlapping cases. Sharing such data is critical to constitutional policing and preserving public trust and confidence in our system of justice. We hope you will consider these points and dismiss the case you filed against Ms. Teran.
