Well, I try to shock them. I try to say to them: don't imagine that investigative journalism is just a case of a knight in shining armour riding about on a milk white steed doing easy things. You have to do difficult things. Journalism of this kind requires sometimes guile. It requires sometimes making hard choices. If you're to get results, then you have to sometimes, you know, go up to the edge of what's acceptable. So you need to have a clear ideas in your own minds of what is acceptable and what's not, what is in the public interest and what's not. So I'm trying to wake them up to the hard choices and the difficulty decisions that I get paid to make.
