L.A. area Muslims say FBI surveillance has a chilling effect on their free speech and religious practices

The Islamic Center of Irvine is a beige stucco building that blends into the rows of office buildings surrounding it. But last week, it became the most publicized mosque in California with disclosures that the FBI sent an informant there to spy and collect evidence of jihadist rhetoric and other allegedly extremist acts by a Tustin man who attended prayers there.

The revelations dismayed mosque members like Omar Turbi, 50, and his 27-year-old son who shares his name. After Friday prayer service last week, while hundreds of others scurried back to work, the pair stood with their backs to a wall and mulled over the news.

"It gives you a little bit of apprehension about who you trust," the elder Turbi said. "Makes you think twice about what you say; what if people misunderstand you?"

Turbi's fears were echoed by other Muslims throughout Southern California last week. Some say a climate of suspicion toward them, fueled by 9/11 and underscored by the latest disclosures of FBI surveillance, is inhibiting their freedoms of speech and faith.

According to Muslim leaders, some people are avoiding mosques, preferring to pray at home. Others are reducing donations to avoid attracting government attention or paying in cash to avoid leaving records. And some mosques have asked speakers to refrain from political messages in their sermons, such as criticism of U.S. foreign policy, said Hussam Ayloush, executive director of the Council on American-Islamic Relations in Anaheim.

"Some average Muslims interested only in praying are avoiding mosques for fear of somehow being monitored or profiled," Ayloush said. "Everybody is afraid, and it is leading to an infringement of the free practice of our religion."

The latest anxiety wave was triggered by an FBI agent's testimony last week that an informant was sent into several Orange County mosques and helped collect evidence against Ahmadullah Sais Niazi. The Afghanistan-born Niazi, 34, is scheduled for arraignment this month on charges of perjury, naturalization fraud and other acts related to lying about ties to Al Qaeda.

A man claiming to be that informant, Irvine resident Craig Monteilh, said last week in interviews and court documents that he served the FBI as a paid informant from July 2006 to October 2007 and used concealed audio and video equipment to record thousands of hours of conversations with Muslims in homes, restaurants and mosques in Irvine, Tustin, Mission Viejo and elsewhere.
