5. U.S. Customs: 500,000 Troops Needed to Seal Border

U.S. Customs and Border Protection Commissioner Alan Bersin has essentially thrown in the towel on efforts to completely seal the U.S.-Mexican border, saying that would require up to half a million troops.

Speaking at an event sponsored by the Center for American Progress (CAP) on Thursday, Bersin said: “We would need on the order of about 400,000 or 500,000 border patrol agents to seal the border.â€
