From what Debbie tells us, it seems likely that Graham is at this very moment peering through his curtains and ever-expecting the arrival of the police.
From the details supplied, it seems that at the time of his ‘knicks down’ dalliance with Debbie, he was above the age of criminal responsibility and that Debbie was well below any age at which she might be thought capable of giving informed consent to the activities.
All that being so, it seems Graham is guilty of a serious sexual offence against a very young child and should, even at this late stage, be brought to justice.
No doubt Debbie will acknowledge her duty to the public at large and to young children in particular and supply full details of Graham’s identity.
