So the dilemma is that if in twenty years time, it turns out the gossip was true, would I be one of the people criticised for saying nothing when I'd heard rumours? As such, I guess all I can do is ask the Police if they are interested in hearing all the gossip I've been told over the year and then if they decide that it is worth investigating, they can.
Sadly as no one has supplied specific names, dates, times or details they will have quite a bit of sleuthing to do before they get anywhere. Had I had credible evidence, I would have picked up the phone immdeiately.
For the record, if anyone has any credible evidence that they feel would stand up in a court of law, I'd be only too pleased to pass it on to the Police. And I would support the maximum sentence that the law could give for any perpetrators found guilty.
