their stupid behaviour bought the schools reputation and the work they're doing into disrepute. i doubt i'd feel confident about giving my parents organs to medical science if i thought it likely that a pile of idiot students were gonna use them to pose with on facebook while i was attending their funeral. i doubt i'd send my kids to a school thats management condoned them taking smiling snapshots of themselves with bodyparts and putting them up on a social networking site for everyone and his uncle to peer at and make flippant comments about, either.
......plus the medical centres reputation probably suffered a blow alongside it- they may well lose referrals/patient confidence as a result of this- cos i bet local people don't want naked pictures of them on an operating table surrounded by students holding scalpels, or of their hemaroids getting banded with a cheesy smiled thumbs up- kid peeking into the frame, showing up on facebook. i bet that possibility will come into their minds, and it'll stick in their heads after they've seen a picture of a family friends kid posing with bodyparts on facebook or been told about it by a third party whose friends sons cousin goes to church with so and so from the picture.
the school may lose funding or struggle to get partner organisations to work with them in future if their students level of tact, respect and behaviour is called into question, which is a bit of a blow for them- that'd affect their standing in the medical community and their status as an institution, and those factors influence peoples career paths "what school did you go to? where are you working now? - oh! the prestigious school of facebook snapshottery? lolz!".
doing something like that makes them look immature and disrespectful. they asked for permission, didn't get it, and so did it anyway. that makes them a safety risk- what other stupid things are they gonna do without permission? "sir, sir! can we huff the nitrous after the patient has gone to recovery?"... "oh, you girls!" and then someone falls off a chair, gets a head injury (maybe someone takes a picture of that and puts it on facebook too?!) .... the school gets sued by their parents.... blah blah blah.
basically those kids behaviour was a liability. once those images are out of the photographers hands they're out of their control. they could end up labelled "hai! in kansas i can has plazenterburger?" on some crappy lolcat website, or made into an animated youtube clip with a hamsterdance backing track and a little sombrero and cigar on the placenta- that goes viral, or who knows what else. a lot of people could get very upset, withdraw funding, cancel medical appointments, clog up phonelines and crash website 'contact us' stuff with their concerns, or sue.... i'm not suprised they got the boot.
