Back when I worked in LE, many apartment complexes would give officers free or reduced rent in exchange for acting as a security guard essentially. At some places this merely meant that they wanted the presence of the officer (and vehicle) to curtail crime and issues, and at others they actually wanted them to go out and respond to other resident's complaints.

This could open up a whole different can of worms for her, the department, and the apartment complex if it's true.
