Long Beach police officials are set to give the City Council’s Public Safety Committee a public briefing Tuesday afternoon about the department’s use of a confidential communications app that has raised the ire of some attorneys because it deleted messages sent among officers.

Councilwoman Suzie Price, who chairs the committee, said she asked for the briefing to get a better idea of how the TigerText app worked and the scope of the investigation city officials have commissioned into its use.

“I’m bringing it to light because the public has a right to know and there’s an interest,” Price said.

Since the LBPD’s use of TigerText was revealed by an Al Jazeera investigation last month, the American Civil Liberties Union has argued the app was illegal and may have compromised hundreds of criminal and civil cases where police have an obligation to turn over evidence to their opponents in court.

At this point, Price said she doesn’t know enough about TigerText to say whether she thinks police ran afoul of those obligations.

“I just want to know more and be educated about it,” she said.

Committee members will be able to ask department officials questions at the meeting, but it’s unclear how much they’ll be willing to reveal until an investigation by an outside law firm is completed. Last week, police said Chief Robert Luna was advised by the City Attorney’s office to drop out of a public event where he was scheduled to answer questions about TigerText.

The Public Safety Committee meeting is scheduled for 3:30 p.m. Oct. 9 at City Hall. It is open to the public.
