But as the Secret Service Director pointed out, that roof was on a slope and we couldn't take the risk of having a sniper cling to such a precarious position.

She never called it a "precarious position". She merely cited safety concerns. There are always safety concerns when putting people on a roof. ANY roof - even a flat one. Heck, professional roofers who work on roofs for a living take safety precautions, often with ropes and harnesses. They don't trust themselves not to misstep and injure themselves. And as I said to the Dope, there are other ways to keep the roof secure. You don't have to put someone on it.

What we need to know is what the plan was to keep that roof (and others in the complex there) secure, and who was responsible for executing that plan. Then we can hold the right people accountable, and not some random folks who may have been there but had nothing to do with that particular roof.
