I fail to understand why you would seek to cast doubt on the alleged victim and then further question the motives, imputing a desire for cash in this case, TWR.
You may suggest that you were only asking the question, but asking the question does appear to suggest that you feel the allegations are made up.
If you work with victims of abuse, it surprises me that you should think a long delay between an alleged event and a formal complaint being brought is strange. CD has described eloquently enough why often happens.
In a climate where only 1 in 20 odd cases of rape actually result in a conviction, when officers in the Mets own Operation Sapphire - the unit responsible for investigating such crimes- fake reports and fail to investigate crimes; when allegations of sexual impropriety by celebrities have been classified as secret by the police, and when the victims of rape are exposed to intimate and hostile examinations of their behaviour and previous sexual history, do you really wonder why victims might be reluctant to come forward? Quite apart from the fact that if it is, for instance, a family member who is the abuser there is all the conflicting emotions and emotional blackmail going on..
The courts will I am sure fully explore the basis for the allegations and will come to a decision based upon the weight of evidence.
Perhaps you should again re-examine your own beliefs and what motivates you to question the alleged victims motives in this case?
