In jail for what?
Lying to Federal agents.
Martha Stewart went to jail for 5 months for this offense.
"causing embarrassment to members of the Lordly class"
This was different to the Balloon family who interfered with the operations of police, state emergency workers, FAA.
The gatecrashers interfered with nobody, and harmed noone (possible exception being those people injured next day when they struck their forehead "Do'h!")
Best kind of hoax: Alan Abel or Horace de Vere Cole would be proud.
