I think what she's trying to say, very badly, is we cannot prosecute every man who ever touched a girl aged 13-16 since 1970.
In that she's absolutely correct. Look at the thread in teacher pupil relationships, think back to the casual sexism in the streets, in your holiday jobs, in pubs and Discos in the '80s.
Our daughters need us to look to the future not waste energy on the past.
We need robust, workable child protection laws, not a climate of fear.
Many activities where 13+ DCs would like to join adult computing, cycling, diving, book or technology clubs are made very difficult by CRB rules.
13-18 and in education -21 year olds do need protection under the law, but most off all they like adult Women need to be believed when they raise reasonable concerns.
Recent horrible cases have not needed a change in the law they have required the police to make assumptions about girls from certain backgrounds.
