LA law enforcement officials, LA Mayor Garcetti react to Dallas Police ambush shootings

Los Angeles police Chief Charlie Beck will make what the department is calling "significant remarks" at Friday's Recruit Officer Graduation Ceremony about the shootings in Dallas that left five officers dead.

LAPD officers will wear mourning bands in honor of the slain officers, Beck tweeted earlier today. He called the killings a "tragedy beyond belief."

"Blue lives matter, they are willingly given and senselessly taken," Beck wrote on Twitter.

Messages of sympathy and condolences were also tweeted by police departments in Anaheim, Newport Beach, Santa Ana, and Long Beach, the California Highway Patrol and the Los Angeles County Sheriff's Department.

"LA County Sheriff sends compassion and prayers to those families who lost loved ones today," said a sheriff department tweet.

Los Angeles Mayor Eric Garcetti tweeted Thursday, "Our hearts are with all of the victims and their families in Dallas. The horrific violence against @DallasPD is an attack on our democracy. All Americans must unite against hate,join together in peace+justice."

California Attorney General Kamala D. Harris said in a statement Friday morning that "the horrific tragedy in Dallas is a grave reminder of the dangers our law enforcement officers face each day in service of their communities."

"I pray for the officers who lost their lives, for their grieving families and our law enforcement brothers and sisters in Dallas," said Harris, who is scheduled to address the first meeting of the Racial and Identity Profiling Advisory Board today in downtown Los Angeles.

"Last night's unspeakable violence reminds me of these words from Dr. Martin Luther King, Jr., 'Darkness cannot drive out darkness. Only light can do that. Hate cannot drive out hate. Only love can do that.'

"Violence only increases distrust and anger. I know firsthand that the relationship of trust between law enforcement and the communities we are sworn to serve is reciprocal. We honor the courage and sacrifice of law enforcement as we continue the important national dialogue around reforming our criminal justice system."

Najee Ali, director of Project Islamic Hope, said Thursday he was "praying for the families of the law enforcement victims who were killed in Dallas."

"We don't support or condone any violence against anyone," Ali said. "That's not the way of the civil rights movement."

Ali had helped organize a rally earlier Thursday calling for justice for the families of Alton Sterling and Philando Castile who were killed in officer-involved shootings in Louisiana and Minnesota.

The LAPD was "closely monitoring" the situation in Dallas with officers ready to respond to any situation from any point, Officer Tony Im told City News Service Thursday.

The department is not on a tactical alert, Im said.
