Of the mind has a link to an article from time.
"Masri also said al-Qaeda has considered plans to "smuggle nuclear materials to Mexico, then operatives would carry material into the U.S.," According to the report, parts of which were read to TIME. Masri says his family, seeking refuge from al-Qaeda hunters, is now in Iran. "
Of course this is "unproved", but this is not one of those things i want to leave up to chance.
I would support the wall IF it was staffed by automated machine guns that killed anything that came over the top or went underneath it.
update: what the crap.
Jim Williams, director of US-VISIT, said Mexican citizens holding Border Crossing Cards, or laser visas, would not be subject to the printing and photographing.
The cards allow Mexicans to enter the United States for short visits, as long as they do not travel more than 25 miles from the border in Texas, California and New Mexico; and 75 miles in Arizona.
I think we have found the problem.
