On the surface, this is a valid question. What rules of evidence exist for a person accused of a crime? If I steal a bike, did somebody see me steal the bike? Is it in my custody? If it was found elsewhere, are my fingerprints on it when they should not be? This all seems very reasonable, until you apply the same cold logic to destroyed lives, manifesting from actions decades ago. If there were two people involved in a sexual assault, and evidence was not collected at that time, did a crime not take place? Are the years of pain, stunted development, and even documentable therapy, voided because of a lack of hard evidence? It’s a problem.
Back to the caring man. He was the head principal of a high school. If there was a sexual assault there, and it turned into a he-said, she-said situation, with no hard evidence, did he turn away and state that he could do nothing for his charges? I sincerely hope not. I would expect that some action was taken short of legal arrest. That’s what is going on now in the realms of entertainment and politics. It hurts a lot when a politically powerful person is taken down, but how much would it hurt if the top football players was dismissed from sports activities, or even terminated from the school, if years’ old accusations surfaced of them sexually assaulting other students? What’s the difference? Power and politics perhaps.
