Williams, however, faced a difficult tenure as he was at odds with the members of the Los Angeles Police Commission appointed by newly elected mayor Richard Riordan. Williams had concerns about Riordan's pledge to add 3,000 officers, and instead lobbied for internal reforms recommended by the Christopher Commission in 1991. He was also not popular with the LAPD rank-and-file, particularly when he did not cut short his vacation in Las Vegas to attend an officer's funeral. However, Williams was the most popular official in Los Angeles and he was credited with restoring confidence in the department.
