"[The Department of Homeland Security] Office of the Inspector General, [Immigrations and Customs Enforcement] Office of Professional Responsibility and CBP's Office of Internal Affairs work together to address possible cases of corruption. This layered approach and collaboration among federal agencies is critical to the mission of professional integrity. Although the percentage of prosecutions for mission related corruption is very small, no incident of corruption is tolerated," Easterling said.
The FBI fears the worst case scenario: Illegal immigrants allowed in by corrupt border officials could be terrorists.
In the last two years, the government says 2,285 illegal immigrants have been caught coming from China, nearly 1,000 from Europe, and hundreds from nations where terrorism is a major concern -- 80 from Pakistan, 10 from Afghanistan, 36 from Somalia, 19 from Yemen, 25 from Iraq, and 26 from Iran.
The FBI worries the border could be the gateway for terrorists who could enter the U.S. without leaving a clue.
"The risk that it poses to the nation is very grave," said Perkins, "in that they do not know what they are allowing into the country or even who they are allowing into the country."
