You mean I do understand how jurisprudence works in the UK. A male person is presumed guilty as per the court of the lynching circuit (public opinion).
In the old days when good sense and good justice prevailed, 20-year-old allegations would not only be thrown out of court, they would not even be considered by police or the prosecution. Even nowadays, when there's no male sex involved (no gold-digging wymmyn), you get rebuffed if you lodge a complaint with the police 20 years after your house was broken into.
