It would probably be helpful for you to actually read the emails. Those are what Hastert and Co. say they saw last year. Then, when you realize they (the emails) were basically innoculous, read the Instant Messages which Hastert and Co. say they saw for the first time last week and then told Foley he had to go.
I'd be interested in your pointing out to me what emails should have prompted Hastert to swing into "action" particularly since the FBI saw the same emails and weren't concerned in the least.
I've read the emails. I find it shocking that you find them "innoculous" [sic]. As a parent, I can tell you that if a middle aged man sent those kinds of messages to my son, I would turn them over to the cops. I would not find such behavior innocuous.
