I agree that the students who did the trashing should be held accountable. Not sure if the "growing culture of disobedience and entitlement" actually exists. It is always questionable to judge a large group of people by the actions of a few. That's how bigotry works.

One problem our culture has is that it keeps young people inactive for far too long, denying them the ability to be adults, and segregating them in youth ghettos. If we want people to be responsible, we need to allow them to DO something. Sitting in a chair being talked at is too passive for adults, and quite frustrating.
