Yes, the Federal Security Director is the senior TSA representative at the airport (or, if it's a small airport spoked to a hub airport, he/she is the senior TSA representative responsible for that airport).

My basic philosophy here is that all TSA practices should withstand the scrutiny of the FSD when challenged. If not, then it's incumbent upon the FSD to take decisive and corrective action. But you gotta let the FSD know that a problem (or perceived problem) exists.
