I had a friend who loved to steal. It gave him a joy he could not equal. It got to the point that he actually found an old abandoned underground entranceway into a university wine cellar (he worked for the university) where he stole bottles of wine from the 1700s & 1800s worth tens of thousands of dollars.
Suffice it to say the FBI came in, set up Surveillance, and caught him. The university did not press charges. They fired him & banned him from the campus for life.
How was it an FBI case ?
