From "Language teachers arrested at U.S. military base":

Two Indonesians and a Senegalese who worked as foreign language instructors for elite U.S. special operations troops at Fort Bragg, North Carolina, have been arrested on immigration charges, authorities said on Wednesday.

The Army said the three worked at the John F. Kennedy Special Warfare Center and School at Fort Bragg. Sgt. Joseph Healy, a spokesman for Army Special Operations Command, said the three had a purely academic role and "were not exposed to any Army special operations tactics techniques or procedures."

Those arrested were Senegalese Ousmane Moreau, 38 and Indonesians Nurkis Qadariah, 34, and Sayf Rimal, 37. They worked for BIB Consultants Inc., "a Florida-based company that provides language instructors to U.S. Special Forces and other military personnel at Fort Bragg."

Now, read this from the AP:

All employees of the company must go through background checks, and checks on the three men "came back clear," Daniel Guillan, director of government and contracting for the company, told WTVD-TV in Durham.

And, we get a reminder:

"What's important to remember is they did not teach any classified materials, and they were not exposed to any classified materials," JSOC spokeswoman Tina Beller said.

As with other past cases, subcontractors - for one reason or another - end up employing illegal aliens, and the feds take their word that those people are here legally. Robin Hayes (R-NC) wrote to Donald Rumsfeld trying to find out how this could happen.
