Something tells me the lawyers of said parents/sponsors of these adults (because midshipmen are adults) would have something to say about parents or sponsors being held liable for "party houses". Let El Commandante know he's not the mayor of Annapolis... he just has a small bit of the land for his school (and he's not even in charge of that).
The comm can't win.
I see a scenario of parents suing the academy for not informing them of their potential liabilities facilitating house parties if they got sued.
If I was a parent with a child in SA, I will be appreciative of the SA informing of situations that my actions could potentially get my child in trouble (i.e. I sign a lease and pay for a house for my child to "relax" with friends, my child gets caught, my child gets punished or even expelled. The SA doesn't have come after me as they have no direct control over what I do, but my child is under their direct control)
