I'm not in a position to know the veracity of this stuff, but I'll be talking to some Border Patrol people on Sunday and plan to ask them what they've heard about this. They've dropped some inferences in the past that makes me think that this is what they were worrying about. Plus, I've thought of how I myself would gain admission to the US if I were Al Qaeda, and joining the hordes flooding in is one major path I investigate. Culberson used the example of the 17-year cicadas, where the strategy is to overwhelm the predators with numbers, saying that terrorists could employ the same strategy at the border.
John, please report what you find out on Sunday right back here if you can. Thanks.
