If we extrapolate the percentage of undetected illegals who succeed in crossing our borders, and apply that percentage to the amount of illegal radioactive materials that go undetected across their border, it's horrifying. Let's hope they're more diligent about preventing illegal activity than we are. I have my doubts about that though.
Snip:....no one knows how many illegal aliens are in America today or how many more are on the way. Not one single government agency or elected or appointed federal official can say with certainty where they live, work or play.
