Each city, county, or state official or department shall assist and cooperate to further the objectives of this chapter. The board, the director of the department, and the probation agents may seek the cooperation of officials and departments and especially of the sheriffs, jailers, magistrates, police officials, and institutional officers. The director may conduct surveys of state correctional facilities, county jails, and camps and obtain information to enable the board to pass intelligently upon all applications for parole. The Director of the Department of Corrections and the wardens, jailers, sheriffs, supervisors, or other officers in whose control a prisoner may be committed must aid and assist the director and the probation agents in the surveys.
