border agents let fake IDs go through

from ap/my way: Undercover investigators entered the United States using fake documents repeatedly this year - including some cases in which Homeland Security Department agents didn't ask for identification.

At nine border crossings on the Mexico and Canadian borders, agents "never questioned the authenticity of the counterfeit documents," according to Government Accountability Office testimony to be released Wednesday.

"This vulnerability potentially allows terrorists or others involved in criminal activity to pass freely into the United States from Canada or Mexico with little or no chance of being detected," concluded the GAO, the investigative arm of Congress, in testimony obtained Tuesday by The Associated Press.
