Los Angeles County Sheriff Alex Villanueva and former Long Beach Police Chief Robert Luna took turns insulting each other in their first debate Wednesday.

There were several references to the ongoing clashes between the sheriff and the Board of Supervisors, including the recent decision by state Attorney General Rob Bonta to take over the Sheriff’s Department investigation into Supervisor Sheila Kuehl, and a deal with Metro.

“I strongly agree that the attorney general stripped the sheriff of this investigation because the sheriff had no business investigating this from the very beginning. You can’t investigate your political opponents,” Luna said.

“Let’s address what Mr. Luna just said,” Villanueva argued. “One, he’s not going to touch public corruption. He’s not going to touch it with a 10-foot pole because his job as a puppet is to look the other way.”

The candidates also disagreed with the way each handled the violence following the death of George Floyd.

“When Long Beach was burning down in the middle of the riots, where was my opponent?,” Villanueva asked. “He acquiesced to what the mayor and the political establishment of Long Beach said, which is ‘Don’t do anything. Don’t offend the looters.'”

“He’s the sheriff of L.A. County,” Luna said. “If he would have been doing his job that day and summoned more mutual aid for the entire area, Santa Monica, Beverly Hills, and Long Beach wouldn’t have suffered the way we did.”

Villanueva also alleged Luna was part of a racist police department, using several visual aids in a bit of show and tell.

“And when people came to Mr. Luna as a supervisor to complain about it, they’re the ones who faced the retaliation,” the sheriff said.

Luna disputed Villanueva’s account of that specific incident.

“A very good detective brought it to my attention, and immediately I turned it over to my deputy chief and we turned it into an administrative investigation,” he said.

After a contentious debate, however, the men did agree on one thing: their favorite TV show, “The Big Bang Theory,” prompting a high-five.
