My thoughts exactly!!! There is no evidence to prove that he has committed any crimes, only circumstantial evidence!!
None of us have access to any of the Police documents, statements, etc. However, even after subtracting a very few dubious claims, the sheer numbers of complaints suggest that he was indeed guilty of some forms of sexual abuse. Given the nature of the complaints, it would be impossible to gather forensic evidence after such a passage of time but circumstantial evidence, collaboration of accounts, verification of dates and places, witness statements, previous formal complaints, etc., all build up a picture of someone who committed sexal abuse over a long period of time.
