Polite as ever, please bother to read the posts you have just quoted.
I did bother to read your post and like you have been following this story for some time. I tend to agree with most of what you had written but it was the following that prompted my 'naive' comment. I agree that Cameron probably has never read the NOTW but he is almost certainly briefed on what goes on bearing in mind it's readership. As ignorant as most of them probably are, they are still voters.
Possibly Cameron had never read the News of The World ? Did he really understand who Coulson was ?
They are either completely naive or arrogant beyond belief. I suspect a bit of both.
It's just that you seem to be sitting on the fence with regard to them being naive or arrogant. This is all about power and who can get it and at what price, ie you scratch my back and I'll scratch yours. Apologies for the naive comment but I don't think Cameron or Osbourne were naive also, they were keen to get into power.
