So in effect, if a couple of people wanted to get someone kicked off a course it would be a fairly simple matter for one to make the accusation, and the other one to back it up?
I would suspect a group of social workers would have the discernment between them to decipher the truth. In my experience people always tell the truth when they realise the gravity of such events. I think it would be far from a simple matter to pull such a stunt and there would be a recognisable history of cause for the people to do so. I would wager such people would be made very well aware what would befall them if it came to be known they had made such a claim. People do some stupid stuff sometimes but not this kind of stuff. You don't risk your entire future to get someone get kicked off a social work course - if you really don't like them let them carry on!
