It seemed to me that when the college professor was followed by the two agents that they (the agents) did not have the intelligence to ask the question "Why did he drive out of his way through a housing subdivision to get home?" He did not stop anywhere that we know of and certainly did not stop at listed houses as though he was interested in buying a house, no, he just drove through a housing subdivision.
Real agents would have asked that question and then assigned someone to see if the professor again went the long way home by first observing whether he turned right or left when he left the campus, and then stationing agents in the subdivision along the route previously taken to see if he stopped at any particular house. The agents were far too quick to dismiss the professor.
I admit I have not seen beyond this episode so if there is an informant notifying the suspect none of this would do any good.
