"This might be different because these things might have flown at the time the movie was made, but not today. In "The Breakfast Club," Andrew (the jock) tapes a very hairy student's rear end together. It's mentioned that when they took the tape off the skin came with it. These days, he probably would have had assault charges brought against him, and his punishment at school would have been much more severe than just Saturday detention. Also, Brian (the nerd) brings a gun to school. It's either a flare gun or pellet gun, I can't remember, but today he would have been expelled."
This is definitely a sign of the times. The type of bullying that Andrew got detention for really did happen in those days and the much stronger rules about bullying that exist today are in no small part due to this. Brian bringing a flare gun to school also falls into this category. Back when the movie was released, such an offense would have warranted detention even though these days it would be considered much worse.
Nikko-chan, I have to say that the scene you described doesn't really bother me at all. In my opinion, calling the cops on Dr. Chase for something like that would reach too far, because the circumstances just don't come together to make it anything squicky. The girl wasn't being exploited or tricked, Dr. Chase was quite obviously not doing it for any prurient reason and it was a quick kiss, not a passionate "movie star" sort of thing. While I understand why it might bother some, I can't say it struck me badly.
