These are the elected leaders of men and women elected to office by their constituents. They couldn't go further because the boy's parents said they wanted his privacy protected and would not allow further investigation. Thye just wanted the leaders to do what they could to persuade Foley to break off communications with their son. They did that. He promised he would have no further contact with him or any other interns or pages .
If our congressional leaders can't be competent administrators, or delegate to someone who is, it's a lot sorrier situation than I thought.
It's absolutely untrue that they "couldn't" go further to investigate. If you read my original post, I made it clear that they could respect the request of the parents, but still check to see if there were problems with other pages or past pages. I've never heard of a competent investigation that consists of asking the accused, "did you something wrong?" and accepting "no" with no further questions.
And where did you get the idea that that was the investigation? They asked if he sent those emails (and those remember were not the salaciousones). He admitted he had. He explained they were innocent and they certianly lend themselves to that interpretation. He was told that the boy didn't want the communication continued and he promised not to.
It was not possible to talk to the biy or to others about the boy's interactions with FOley because the parents refused.
