 A reporter asked the exact same question I'm asking in a different way. I'm asking, where was the aerial surveillance? Where was the drone that would have seen this attacker walking up a ladder, getting on a white building? She just says, how did this happen? The guy has absolutely no answer because he can't fathom either how such an incredible lapse in security could have had with such a high threat protectee like Donald Trump. Listen to this. From what you can read about him, it sounds like long course men only knew he was up there.
