I think these events have always gone on but not reported. We live today in a 24/7 media frenzy with rapid electronic messaging every where.
No doubt there are some bad people but also there are good people caught up in all this.
Much of the fall out from Saville, whos exploits only came to light after he died remember so he was never tried in court (unlike GG), stem from an era where sexual abuse was rife and part of the culture.
No coincidence that Top of the pops features where young gilrls and boys no doubt were grovelled by perverts routinely, some would have enjoyed the experience of appparent adulthood, some would have been traumatised by it.
Same with groupies volunteering for sex with so called superstars, many must have been underage and one or two so called household names from the past must be dreading the long arm of the law calling.
Some will have noted my loathing of unprofessional media types who report without checking, remember we are all innocent until proven guilty and great care should be exercised before things are put in the public domain.
