Yea, I get the analogy they were making, I just was pointing out that it's not totally correct. The police are not going to give you an award if you show a picture of weed in the house. They would need to see the weed in the house and collect it as evidence. If anything, showing a picture of weed in the house and then having the police find no weed there may give them probable cause to search the plumber for the weed...

Same with digital files, if the same Geek Squad member keeps "finding" evidence they plant on peoples computers, the Geek Squad person is opening themselves up to a ton of risk. In order to plant the digital files you are by definition in possession of the banned files and are breaking the law. Any good law enforcement agent would realize that the same person is unlikely to find illicit files and that it is more likely that they are planting evidence.

The point is that there is not an easy payday. To get paid you must break the law by possessing the files. Plus, just copying the files to the persons computer would leave an obvious trace considering they know when the Geek Squad was there and know when the files were copied.
