There is lots that could be said about the Jimmy Savile affair, but I want to add some comments on the role that status played in creating and maintaining his persona, and (presumably) protecting him from prosecution.
Firstly Savile cultivated relationships with those at the top of society - politicians, the church and royalty. This brought him both Papal and Royal Knighthoods in his lifetime, and visits to the Prime Minister. Mrs Thatcher appeared three times on Jim'll Fix It in 1976, 1983 and 1985 - an extraordinary indication of the way Savile was able to get the truly powerful to work with him. Interestingly however the claims that Savile spent Christmas with Mrs Thatcher at Chequers may be just that - claims. The exhaustive Thatcher Foundation website certainly records meetings between the two - about Stoke Mandeville and with an NSPCC official - but not weekends at Chequers.
Savile's victims were broadly, but not exclusively, those towards the bottom of society - children in care, and those in other institutions such as Broadmoor. That pattern of offending is not unique - indeed it could probably be found amongst a small number of upper class men at any stage in the last couple of centuries. It is 'Victorian Values' personified.
Savile though had not been born with a silver spoon in his mouth - he had worked his way to the top. The addition in Savile's CV and key to his modus operandi was his understanding of that most twentieth century of concepts - celebrity. That celebrity gave him another area in which to meet young women - the music business. It is probably outside the remit of any investigation that goes public, and not in keeping with the tone of the media's coverage, but my guess is that much of the sex Savile had in this setting would have been consensual, and lots of people would have known about this. Far more than those who had concerns about abuse.
Savile wore his celebrity and work for charity as a cloak when awkward questions were raised. If you raise as much as £40 million for places like StoKe Mandeville - as Savile did - you change countless lives for the better. That image, combined with establishment friends, is a powerful combination. It is certainly more powerful than the status of a teenage girl abandoned in a 1970s care home on a corrupt little island like Jersey.
