Law enforcement has a number of informants working for it and the companies that already pay their paychecks, like UPS, for example. It also has a number of government employees working for the TSA, keeping their eyes peeled for "suspicious" amounts of cash it can swoop in and seize.

Unsurprisingly, the FBI also has a number of paid informants. Some of these informants apparently work at Best Buy — Geek Squad by day, government informants by… well, also by day.

According to court records, Geek Squad technician John "Trey" Westphal, an FBI informant, reported he accidentally located on Rettenmaier's computer an image of "a fully nude, white prepubescent female on her hands and knees on a bed, with a brown choker-type collar around her neck." Westphal notified his boss, Justin Meade, also an FBI informant, who alerted colleague Randall Ratliff, another FBI informant at Best Buy, as well as the FBI. Claiming the image met the definition of child pornography and was tied to a series of illicit pictures known as the "Jenny" shots, agent Tracey Riley seized the hard drive.
