Los Angeles County Sheriff Lee Baca was sworn in Monday for a fourth term, and he said he did not expect it to be his last.

"I'm going to live to be 100," Baca, 68, said after a ceremony attended by dozens of his deputies and a smattering of state and local officials. "My mother is 92."

As for the coming term, Baca said his goals include expanding educational programs in county jails, moving sheriff's headquarters to the historic Hall of Justice downtown and continuing to cut violent crime.

Gov.-elect Jerry Brown administered Baca's oath, opening his introduction with grim humor.

"Not a lot to say... You're going to get a lot of surprises in the next couple weeks," Brown joked, later telling the crowd he'd just come back from "slicing and dicing all those programs that are near and dear to you."

But Baca was all smiles. The gathering had been moved inside the Cathedral of Our Lady of the Angels because of rain. Baca's son, a police officer, led the Pledge of Allegiance, and several of his grandchildren sat nearby.

The event's emcee, Fox 11 reporter Christine Devine, called Baca "my mentor." During is speech, the sheriff acknowledged "mistakes," but said "you cannot be creative and not make mistakes."

Baca made a historical allusion to the Wright brothers, who he said were considered "fools" before their first successful flight. Looking forward, Baca said he plans to run for a fifth term and maybe more, as long as his health holds up.

Before the ceremony, Baca took his standard morning run of about seven miles.

"It was raining too," he said. "Man, it was freezing."
