Let’s be honest, we know virtually nothing. It’s all very well blaming the BBC, blaming the mother, blaming the presenter. Actually, so far we don’t know what information the BBC initially received or what they did with it, we don’t know whether the mother’s motives were what she says they were, and we don’t know whether the presenter believed the young person was over 18, how they met them, whether they were one of many people the young person was potentially selling services to, whether they were being blackmailed - it’s all speculation and gossip. All we actually know is that a presenter has been suspended pending further investigation.
The Sun should have gone to the police, and used their powers directly with the BBC to force action in my opinion if they believed the mother and had the young person’s permission, not indulged in irresponsible journalism that will destroy lives.
