There will be no satisfaction in "I told you so".

An ABC News investigation of the flawed U.S. refugee screening system, which was overhauled two years ago, showed that Alwan was mistakenly allowed into the U.S. and resettled in the leafy southern town of Bowling Green, Kentucky, a city of 60,000 which is home to Western Kentucky University and near the Army's Fort Knox and Fort Campbell. Alwan and another Iraqi refugee, Mohanad Shareef Hammadi, 26, were resettled in Bowling Green even though both had been detained during the war by Iraqi authorities, according to federal prosecutors.

Alwan and Hammadi's names and fingerprints were checked by the FBI, DHS and the Defense Department during the vetting process in 2009 and "came in clean."

The Iraqi database is more extensive and complete than what we have for Syria.

The previous reaction:

As a result of the Kentucky case, the State Department stopped processing Iraq refugees for six months in 2011, federal officials told ABC News – even for many who had heroically helped U.S. forces as interpreters and intelligence assets. One Iraqi who had aided American troops was assassinated before his refugee application could be processed, because of the immigration delays, two U.S. officials said. In 2011, fewer than 10,000 Iraqis were resettled as refugees in the U.S., half the number from the year before, State Department statistics show.
