So what or who are they protecting? A free american citizen President in the shape of a USofA corp person circa 1910?
The only thing in the Whitehouse is a Trotskyite/Alinskyist/Maoist collection of bitchboys and boybitches from some dump where they now keep slaves and shoot persons without due process.
Well now that we think about it more carefully the empty house does need sealing off from the great unwashed just in case anyone really finds out that the president is an alien, spouting alien beliefs, using alien language and is a total fauxersatzsyntheticprotoYahweh Turing Fail workshy roboboybitch from Batavia, foaled from a workshy moneybitch dolly and totally unfit to be in charge of an iced cream parlour.
In fact if we look carefully at the so called leaders of the western shitheaps they would likely have all their customers coming out of the cornetto cafes with first degree burns and deny all knowledge about it as the streets filled with academic Hollyweird crisis actors faking frost bite.
