I agree with your answer as the change agency is new obligation for leadership achievement. Actually not only high ranking level-managers can drive managerial change but any person with desire of becoming a catalyst at work may undertake the role of the change agent. Any title given to the person who undertakes the task of initiating and managing can change the organization. When given a chance to manage the police department you should be confidence because you are special and you can do it. At fast you should learn the character of other officers and get to know them well then everything will run smooth. Also the department should take initiative of letting people know they are appreciated.
