A coalition of community groups is demanding Long Beach fire its police chief and city manager after the revelation that police officers were using an app that automatically erased messages they’d sent each other, a move that critics say could have compromised hundreds of civil and criminal cases .

The groups will rally in favor of the firings and a slate of other demands during a City Council meeting Tuesday where members of the council are scheduled to evaluate City Manager Pat West’s performance.

The pervasive use of TigerText to automatically delete information that could incriminate police officers is just one symptom of a exploitative, violent, and racist police department.

Organizers say the coalition includes Black Lives Matter LBC, the Long Beach chapter of the Democratic Socialists of America, the Stop LAPD Spying Coalition and family members of those who’ve been affected by police violence.

“We’ve really been outraged, so we came together recognizing that we have the same goals,” said James Suazo, a member of the Democratic Socialists of America.

The groups are also pushing for the LBPD to reopen all of its cases since 2014, which is when officers started using the messaging app called TigerText, according to city officials.

The coalition wants a particular emphasis on cases that involved “injuries and killings by police, in order for those impacted and their families to be able to ascertain whether information shared via TigerText has a material bearing on these cases,” Suazo said in an announcement Monday.

The LBPD’s use of TigerText was revealed publicly last month in a report by the news network Al Jazeera.

Police Chief Robert Luna has suspended use of the app and the city says it’s launched an investigation into how the app was used and why it was approved on 145 city devices including phones used by homicide detectives, command staff and other specialized officers.

The coalition’s slate of demands also includes pulling money out of the LBPD and putting it into programs for childhood education, mental health treatment and a solution to the local affordable-housing crisis.

“It’s clear that the LBPD cannot make good decisions with their money that build public trust,” Suazo said.

Suazo said he expects at least 50 people to rally outside City Hall starting at 4:30 p.m. A smaller group of protestors will address council members inside at 3:30 p.m. before the council heads into a closed session for West’s evaluation.
