WASHINGTON - A prominent national Islamic civil rights and advocacy group Saturday called on US authorities to explain why more than 2,000 immigrants from Muslim-majority nations were singled out for questioning in 2004, despite statements at the time denying the use of religious "profiling." The Washington-based Council on American-Islamic Relations (CAIR) cited newly-released government data on more than 2,500 foreigners interviewed in the fall of 2004 as possible national security threats. After being questioned about their views on the United States and what was preached in their mosques, none of those interrogated were charged with national security offences, it was pointed out. In 2004, government officials responded to concerns about the interrogations by saying they were engaged in an effort to disrupt terror plots and rejected accusations of profiling. The new data shows however that "79 percent of the suspects were from Muslim-majority countries." "Government agencies seeking to partner with American Muslims make that partnership harder to achieve when they appear to engage in racial, ethnic or religious profiling," said CAIR Legislative Director Corey Saylor. "American Muslims support strong and effective law enforcement measures that respect the Constitution and protect the civil and religious rights that we all cherish." Saylor added that these "disturbing revelations" are of particular concern because of new Justice Department guidelines that may allow religious and ethnic profiling without evidence of wrongdoing on the part of those being investigated.
