During the first three books, Chief Bulton is the Chief of Police in charge of security at the entrance to Welltower. He has hundreds of other officers under his control and maintains patrols to prevent unauthorized entrances and exits from Welltower.
When Selda and Doctor Herstand visited him, they both felt he was a good man and a good chief. He gave them what information he knew regarding the death of Kimm; he felt that the murderers were agents of Serrin. They gave a recommendation to his boss.
Sometime in the ensuing 21 years between books 3 and 4, he was moved outside of Welltower and made a chief investigator for Protective Services. He had responsibility for the protection of Fvlet and his family and the investigation of the failed assassination attempt.
