It seems that among the illegal community the use of stolen identity is very common. In many Mexican neighborhoods of large cities, one can purchase fake green cards, stolen S.S. cards, birth certificates and other documents that are being used my illegals to secure employement. The most recent case in the news, was that of a police officer in Alaska, who had been hired five years ago by using the stolen identity of a U.S. Citizen. He was indeed an illegal Mexican and was discovered when he tried to revalidate his U.S. passport. The police department in Alaska is now facing serious legal problems brought by people that had been arrested by the impostor in the last 5 years. The F.B.I. should conduct a large scale investigation to find out how extended is this practice.
