A PP upthread has a valid point when they say a real dark force in the media establishment is Rupert Murdoch. This is true. No one person should ever have been allowed to grab the amount of media power this man has - which brings with it a likely unique opportunity to influence others on a mass scale.
But you can bet on it that as far as establishment dark forces are concerned, he isn't the only one.
In the media, broadcasting and film industries, the protection of male sexual proclivities at all costs - including at the expense of women and children - is one such, particularly if revolting practices like the 'casting couch' are common knowledge.
A few have fallen in their swords - and they don't have to have gone so far as to commit a criminal offence to be deemed unfit for post and dismissed. But persistent rumours have swirled around certain names, and as 'national institutions' they are still being supported and protected. Once these men cark it, only then will the right questions be asked alongside the inevitable protestations: 'I never trusted him, he always gave me the creeps'.
Pointless ruminating when it's too late. This rot needs flushing out from the top down.
