Faced with an FBI investigation into the jail system and mounting criticism over his handling of the crisis, Baca said in a long interview with The Times that his command staff has at times left him in the dark about the jails' woes.

He noticed only during a recent visit to Men's Central Jail that video cameras purchased more than a year ago to help monitor deputies and inmates had not been installed. The 69 cameras are still in boxes in a captain's office. Baca has since committed to installing them by the end of the year.
"I am the ultimate authority here," he said. "There's no excuse for such a major project as this going undone."
Baca's statements offer a marked contrast to his reputation as an energetic and progressive-minded executive. They also provide a rare window into Baca's struggles to run his sprawling department. The Sheriff's Department operates the nation's largest jail system, with custody facilities across the county, and provides police patrols for scores of communities and security for L.A.'s mass transit system.
Baca said his subordinates have insulated him from "bad news." He said he scolded the subordinate responsible for overseeing the camera project.
"Everyone wants to handle it; they believe it's their job, but handling it and not telling me leaves me vulnerable," Baca said. "I have to be informed."
Interviews by The Times with sheriff's and county officials suggest that Baca's management problems at times extend beyond jail matters.
Those who know him well say he's succeeded in areas in which he is most engaged, such as immigrant outreach. Violent crime has fallen in areas patrolled by the Sheriff's Department, notably in Compton, where Baca has focused extra resources. He takes calls from members of the public, even entertaining rants from a group he calls his "habitual callers."
At public events, he will hear out complaints against deputies.
His willingness to listen and reach out to others has made him a popular figure in some quarters. Voters have reelected him by large margins three times. But even Baca's supporters say he runs into trouble when he fails to take a close interest in important matters.
For example, Baca recently boasted that there were no citizen complaints alleging racism by his deputies in the Antelope Valley. He spoke at a news conference at which federal authorities were announcing a massive civil rights investigation into allegations of discrimination by deputies.
In fact, residents had been complaining for years. A sheriff's spokesman later had to say his boss was wrong.
Some say Baca, after 13 years in office, must take more responsibility for his bureaucracy's failings. County Supervisor Gloria Molina criticized the department's failure to carry out numerous reforms suggested by two watchdogs over the years.
"I'm sure that he's frustrated by his bureaucracy. But there's a point in time when it all lines up and it tells you that you've got to step in and take some action. And that's today. He's the only one who can do it," said Molina, who described Baca as a "sweetheart." "I think he needs to be much more aggressive."
Among the reforms Molina says the sheriff needs to make: putting new limits on when deputies can use head strikes against inmates, intensifying supervision by having sergeants regularly walk the jail floors and requiring nurses and other medical staff to report suspicious inmate injuries. She said the recommendations had previously been made by the county's Office of Independent Review and Merrick Bobb, a special counsel to the Board of Supervisors on sheriff's issues.
The FBI is investigating reports of abuse and other misconduct. The U.S. attorney's office more recently demanded a large volume of documents on deputies and others working in the jail, including reports of force used on inmates, since 2009. The FBI probe includes allegations that deputies carved racist initials into one inmate's head and broke the jaw of another inmate.
