Vicki Gregg is stated to be a former LAPD officer that became an FBI agent and novelist. As such, she would not be reinstated into the LAPD to assume command of a unit. At best, she would be used as a consultant or serve on a task force. As a non-LAPD employee, she would have no supervisory authority over the LAPD personnel. In actuality, the LAPD would temporarily assign another Lieutenant to supervise the unit while Beth was out.
