Yes there was....
A Bangladeshi Muslim man named Fakhrul Islam was among a group of 13 illegal aliens arrested near Brownsville, Texas, just across the border from Mexico. Border Patrol agents have said that one of the men detained along with Islam was a member of Mara Salvatrucha, a violent Salvadoran criminal gang with more than 300,000 members across Central and North America, including powerful enterprises in several major U.S. cities. "In July, Adnan El-Shukrijumah, a high-ranking Al-Qaeda leader and one of the most wanted terrorists in the world, was spotted in Honduras meeting with members of MS-13. Attorney General John Ashcroft has said that El-Shukrijumah, who he has described as a 'clear and present danger to America,' is seeking ways to infiltrate the U.S. via the Mexican border, and is willing to pay top dollar in order to do so."
That might have been why the border was so tight...but knowing the border guards, who wouldn't open fire on anyone trying to cross the border, wouldn't it be smarter to build a giant wall right next to a new Panama Canal...oh wait, hopefully Hillary won't run and sell it to the chinese.
