I think you are correct that Hastert, knowing only that there were emails with non-sexual content, acted the way most people would have.

Knowing as he must have known that Foley was gay, he could have been more curious about what else was out there - but I don't think that's a job requirement AND if he had mounted an investigation based on the emails only and over the objections of the boy's family, he would have been crucified for "homophobia".

It all depends on which emails Hastert saw. Some of them are supposedly very crude.
