It's a scandal how people abused positions of power
The headlines are bad enough, but what lies behind them is worse still. We are looking at the decay of institutions, of trusted institutions, on both sides of the Atlantic.
The first sign can be routine in its banality.
From Washington we learnt, for instance, that General David Petraeus must stand down as director of the CIA for having shown, in his words, "extremely poor judgment by engaging in an extramarital affair".
This was unfortunate, but such things happen. But then it turned out that another senior officer, General John Allen, who was due to be named as commander of US forces in Europe, had had "inappropriate communications" with a certain Jill Kelley, a self-appointed ambassador for servicemen stationed in Tampa, Florida.
What happens to the respect that army commanders must earn from their soldiers if they are to ask them to risk their lives in battle? Doesn't a moral rot that spreads and insinuates itself everywhere deaden the spirit?
In the case of the BBC, the first revelations of the Jimmy Savile case were disturbing enough. The corporation engaged in a passive cover-up by failing to act when presented with incriminating evidence. It was silent when it should have been in touch with the police.
Then it turned out that it wasn't only Jimmy Savile. Nevertheless, you could still comfort yourself by the observation that that was then and now is different.
But then came the Newsnight calamities and the new director-general's extraordinary performance on the Today programme.
It wasn't that any moral failing became evident, but something nearly as deadly to institutions - 'job conditioning' - so that the world is viewed in a distorted way.
George Entwistle's replies to John Humphrys' questions were the product of some 23 years of continuous employment by the BBC in a series of increasingly important executive positions.
It was Entwistle's BBC training that led to him failing even to know that Newsnight was planning to run a paedophile expose.
It was job conditioning that meant he gave a low priority to reading the newspapers, so that he missed a warning that the Newsnight programme was seriously flawed.
He had been taught to be all big picture and no detail - a fatal combination. So, no doubt, has the entire upper tier of the BBC management team learnt the same unfortunate lesson, for it can be safely assumed that they are subject to the same conditioning.
But what is one to make of an institution that is neither an army, nor a giant broadcasting organisation, but rather a series of financial and commodity markets where the main users are large companies, such as banks and energy companies, who, it is alleged, have got into the habit of working together to manipulate prices?
These may be big boys' markets, where single transactions are worth millions of pounds, but their trends nonetheless affect, say, how much our mortgages cost and how much we pay for our gas and electricity. So we need these markets to be honestly and efficiently conducted. And the evidence is accumulating that they are not.
In the case of the market in which banks lend to each other for short periods, where a daily rate is established that effects numerous transactions around the world - the London Inter-Bank Offered Rate, the famous Libor - Barclays has already pleaded guilty to manipulation and been fined.
Regulators in at least seven countries are now investigating the rigging of Libor and around 20 major banks have been named in investigations and court cases.
Now it is alleged that the same sort of fraudulent behaviour has been taking place in the gas and electricity markets. And if bad behaviour is proved, no doubt some individual traders and department heads will be punished.
But this would miss the main point. It is boards of directors who set the standards by which their companies operate. It is they, seemingly respectable, living in nice houses, stalwarts of their communities, widely respected, solid citizens, who are responsible for the decay of their institutions.
And there are others in grave difficulties - the police and parliament among them.
We know what is happening, or at least we are gradually finding out. But we don't know why.
Are they each special cases with their own particularities? Or is there a general explanation?
