Does anyone remember the name of a documentary (World In Action/Panarama/This Week - a mainstream broadcaster anyways) from the late 70's? It was about the 'old main drag', about London's Piccadilly and the men who preyed on teenage runaways there... including some who had set up Charities and homeless shelters to facilitate their rotten exploitation. As I recall it resulted in investigations, prosecutions and convictions. I'm sure it must be up on YouTube and it would be interesting to see again in light of recent developments. Thanks.
