Following the 1993 World Trade Center bombing , Rescorla invited Hill to New York , where he hired him as a security consultant in order to analyze the building 's security . Although no arrests had yet been made in the case , Rescorla suspected that the bomb had been planted by Muslims , probably Palestinians , or that an Iraqi colonel of engineers might have orchestrated the attack . Hill let his beard grow and visited several mosques in New Jersey , showing up for morning prayers at dawn . He took on the character of an anti-American Muslim , speaking fluent Arabic , in order to infiltrate and interview the other visitors to the mosques . He concluded that the attack was likely planned by a radical imam at a mosque in New York or New Jersey . Followers of Sheikh Omar Abdel Rahman , a radical Muslim cleric based in Brooklyn , were subsequently convicted of the bombing
