This would be LOL funny if it wasn't so disgraceful. 'Vowed to do better"?? It wouldn't take an awful lot to do "better".
You are right vowing is not enough. There have been procedures in place for quite some time on how to handle accusations. I am assuming these are not accusations that could just be dismissed out of hand but warranted being reported to law enforcement. That this was not done is disgraceful and inexcusable.
