Actually you have to wonder if they would really do their job for the Clintons were someone to try and harm them. Can you imagine their idea of the SS agent catching a bullet for the very people that crapped on them for the last 9 years ???
I seriously don't think that they would do it.
I could visualize them going "bullet? what bullet? did a bullet go by here? Oh, THAT bullet! Sorry, 'bout that, chief!"
NEVER crap on somebody who you're going to have to rely on to save your butt
