Why didnt Trask get the Police involved after the Vandalism?
Thats one thing i never understood after watching the movie, how Trask never contacts the local Police Department after the incident involving his gift Jaguar because Destruction of Personal Property/Vandalism is actually a Felony and a pretty big deal, i know this because my grandfather was a Cop and he and my mother watched this movie with me when it first came out and they said how the suspects could all be arrested for refusing to cooperate with the investigation.
So when people refuse to tell what they saw and make things hard on everyone you let the Police start asking all of the serious questions, cross examine everyone, lie detector tests etc and the full works, threaten arrest, Vandalism and destruction of private property is a pretty serious crime and carries a few years in prison, not something college kids would want to risk for just a mere prank, yet this can all be swept under the rug if someone cooperates and rats on the others, snitching is not bad when you avoid jail or prison time.
Trask never seemed to realize that if the students like George and Charlie wouldnt cooperate that he could just invite the Police to attend his questioning of them in his office the first time, let them ask some questions too, then invite the local Police to the student committee and sit in on the proceedings, get them personally involved in the matter, let them treat it as a criminal investigation and threaten jail and prison charges for all parties involved in the Vandalism, that would make refusal to cooperate criminal and very stupid for the people involved, Charlie might not go to Harvard if he failed to help the Police in their criminal investigation, and George's daddy couldnt save him from going to jail for lying to the Police.
The other three that were guilty would be in jail and be getting molested and butt raped, they would regret their prank after the police busted them and threw the book at them, Charlie owed them nothing.
