Steve,

A policeman saw pornography on a computer and, technically against the rules, felt obliged to blow the whistle and tell the truth about it,

Who to?
He only told Green himself, so he did not break any rules until he went public nine years later.
He did not report it to the government or to the Tory Party or anyone else at the time.

You can decide which of the two men possessed the greater integrity and who was more honest. It isn't hard.

Not now it isn't. We know it was Green who lied.
I refused to accuse either in the absence of any evidence.

You people operate on prejudice and witch hunt. That is all I was critical of.
