Revealing mistake: When Ed Rooney walks up to the girl in the arcade, he wouldn't have known it was Ferris, as he'd only seen him in the grey coat and hat outside the school when he was picking up Sloane Peterson.
Suggested correction: Odds are very good that Ferris has worn that particular jacket to school regularly. Rooney would have seen him in it.
Plot hole: When Jeannie encounters Mr. Rooney at her house, she attacks him and calls the police. Later, the police pick her up for filing a false report. Why? Surely they would've seen signs of an intruder such as a dropped wallet on the floor and footprints in the mud right next to the house.
Suggested correction: Without knowledge of what happened when the police visited, it's impossible to call this a plot hole. It might be that the police knocked on the door, Jeannie answered and explained that by the time they got there the intruder had gone. She could have got angry at them like she did on the phone. Maybe they arrested her there and then, without entering the house or searching the grounds (for someone they'd just be told was no longer there). Who knows? Unlikely sure, but not impossible.
