Indeed. With the Mexican border as bad as it is, there's no telling what sort of scum have slipped through.
But hey, the Cold War is over and the Soviet Union doesn't exist anymore, so there are no more threats to America, right? We don't need border security, anyone who wants in should get in, and anyone who wants border security or believes there are threats to America is just a far-Right, neo-Nazi, flag-waving racist.
