What did they know and when did they know it?

Regarding the SBC abuse scandal, I wonder about major players like Al Mohler. He rose through the ranks at rocket velocity. He's held top positions in the SBC for many years now. 

Did he have no inkling what was going on? Never heard rumors? Nothing through the grapevine? No victims or friends of victims ever confided in him?

When the Cardinal McCarrick scandal broke, people asked "What did they know and when did they know it?" How could some of his associates and superiors not know what he was up to? And it turns out that they did. The SBC needs to ask itself the same hard questions.

Perhaps some people did confide in Mohler, but no one who spoke to him was prepared to go on record.
