There are ways to battle waste, fraud, and abuse that do not resort to 'parachute into the middle of an agency, fire most of the staff and then walk away congratulating yourself because you eliminated waste, fraud, and abuse.'

Sure you lowered the spend of the agency, but you probably, by removing all the people who actively investigate/police waste, fraud and abuse, promoted more people to defraud the agency and not get caught.

Congratulations, you played yourself.
