I retweeted this, but wanted to comment on it also. The following paragraphs are the core of the issue.
In the Irvine case, Monteilh's mission as an informant backfired. Muslims were so alarmed by his talk of violent jihad that they obtained a restraining order against him.
He had helped build a terrorism-related case against a mosque member, but that also collapsed. The Justice Department recently took the extraordinary step of dropping charges against the worshiper, who Monteilh had caught on tape agreeing to blow up buildings, law enforcement officials said. Prosecutors had portrayed the man as a dire threat.
Compounding the damage, Monteilh has gone public, revealing secret FBI methods and charging that his "handlers" trained him to entrap Muslims as he infiltrated their mosques, homes and businesses. He is now suing the FBI.
Here is the case of the government sending spies into organizations, just because they are a certain type of organization rather than actually having a real reason to do so -- in short profiling. I'm glad that the congregation did what it did to prove this type of approach less-than-effective!
Hurray for the "American Person" in the Mosque showing us that we should judge individuals, not classes of people.
