"If I provide the party, at least I'll be in control of the situation"

So many parents host parties for their underage kids with the thought that if they are in control of the situation, nothing bad can happen. While this party took place at a hotel and not in a home, the thought behind it is still the same.

Clearly, these parents didn't want anything bad to happen to the students at this party. Clearly, also, they did not provide the supervision necessary to prevent these incidents.

How can we educate parents about the problems created by being "the cool parent"?
