I think there is some equivocation going on between the situation in the 90s, and pre-1967.
In the past, gay men did end up convicted of sexual offences for consensual relationships, because the police and the public prosecution, and the country thought it was right to interfere, whatever the other partner said about it. It was a paternalistic attitude, I suppose you could say.
That was ended in 1967, provided the men were over 21. Under John Major, an amendment was put forward to drop the age of consent for males with males to 16. It failed, and the age of consent was dropped to 18 in 1994 as a compromise.
Labour were elected in 1997, and the new government pressed to drop the age to 16 from basically the moment Tony Blair walked through the doors of number 10. Checking the records, the amendment got through the House of Commons in June 1998.
So, would you as a prosecutor in 1999 have been keen on prosecuting a teenage boy for willing sexual activity with another boy, to please the other boy's parents?
The fact is, we do not prosecute for willing sex between teenagers in this country, because
a) the age of consent is to protect children. Criminalising children themselves for underage sex would be abusing a law to protect them. This precedent was declared in Victorian times, when a court ruled the law against incest should not be used to pursue victims.
b) the logistics. To successfully prosecute, you need physical evidence that sexual activity happened, and for the victim to give evidence, that convinces the court that she or he was not consenting, and could not have been thought to be consenting. At this point, may I remind you that adult men successfully escape conviction with great frequency, because they convince the jurors that their underage victim did want to have sex?
Is it being claimed that another 14 year old boy was marched down to the police station by his homophobic parents, where the police forced him to have an intimate medical examination with a police surgeon, so evidence could be collected? Is it being claimed that a 14 year old boy was forced to take the stand against his boyfriend and he LIED to the court about it being mutual willing activity? Moore and his defence team would have, obviously contested that, wouldn't they?
But the court decided to disbelieve the defence, you think?
Weird, because in my experience, when teenage victims tell courtrooms that they were abused, and the defence says "nah, victim was totally up for it", the defence normally wins the day, due to burden of proof.
