Definitely they are to blame for acting unprofessionally and breaking team rules in the second-dumbest way possible. Definitely they are to blame for thinking with their dicks. My sympathy extends as far as knowing what that (thinking with one's dick) can do to many (most?) young blokes. Their careers in Australia are probably over - and rightly so. Hope it was worth it you seedy idiots.
Like someone else said, a friend of a friend was done for something similar. Met a couple of 17 year old girls one day in the Valley, took them back home, smoked some weed and banged them. He was only 20 at the time. Problem is they were in school uniform. He went to jail for it, I think mainly because he gave them drugs. It's really hard to fathom what the hell he was thinking until you can honestly put yourself in that same position and ask yourself.. would you? I know I wouldn't now, but at 20? It's an uncomfortable question.
Anyway this is off topic because this bloke I'm talking about was not representing two layers of employer as a public person inside a school in a position of authority and specifically there to generate good will and PR.
