"How did those illlegals get a ticket to fly on the airlines and board, if they are illegal?"
They use the Mexican matricular card. The House of Representatives has been having a hearing this week on Mexican IDs.
http://www.freerepublic.com/focus/f-news/936316/posts The last paragraph on that page will explain that the Mexican IDs can be used to board airplanes. Homeland Security,airport security, congress, the presidente and the FBI are all aware. The only people that are unaware are the American passengers who fly.
There you go. It helps to ask questions. Mexico now sets our foreign and domestic policy. Just in time for homeland defense, Mexico comes up with it's own ID. I'm sure that was just coincidence. And I'm sure our officials knew nothing about it. You know damned well there were back door communications on this.
