 who are trained enough that they're being entrusted with security at a presidential campaign rally, that they can't get on a slope route? I mean, is this how it works out in the field? If there's a hostage situation at a bank and you need a sniper posted on a roof to take out the bad guy, would you look up and say, oh, never mind, we can't. All the roofs, you know, you see there's a slight slope on that roof. We can't do it.
