GPS used to spy on Detectives

Jacqueline Seibel:

Suspicious that his detectives were not hard at work solving the latest crimes in Muskego, Police Chief John Johnson spied on his own investigators using high-tech surveillance equipment usually used to keep tabs on drug dealers and gangbangers.
Secretly placing a global positioning system tracker in a squad car shared by the department’s two detectives, police supervisors learned that the pair were driving to a tanning salon, shopping at the Geoffrey Beene Outlet Store in Kenosha County and running personal errands while on duty, according to reports released Tuesday.

This is not a new story, there have been previous examples of GPS (Global Positioning System) used to track rental car users among others.
