"I'm still chortling at the idea that the big money is in low-carbon, when it comes to energy."
I don't understand that. What low-carbon?
'Who or what doesn't allow the DM to print what it wants? '
No it is not the law, it is unspoken rules. They have to play the game and know the rules. Just as the Jimmy Savile scandal was not revealed. The same type of people control the game. It is informal, not formal, there are no explicit rules, it is more subtle and all-pervasive than that.
'Hints are used by people who can't justify what they say'
No, hints are warnings, hints are help, hints are as far as they can go.
Look at the Rochester scandal. Lots of people knew and yet it could not be brought out fully in the open. Journalists must have known - local journalists and hence national journalists too, but nothing was done for years. There are lots of people responsible indirectly and even directly.
'When there is an information vacuum'
There is a truth vacuum, and hints are warnings that try to break the barrier as far as they are able to.
Right now on BBC Newsnight we are being told that in some parts of Greater Manchester "child exploitation is the new social norm".
It is disgraceful and clearly lots of people have known about this and the report says that Rochdale is not an isolated case.
