Investigators seeking to uncover terrorist plots for years have walked a fine line between keeping tabs on the Muslim community and alienating the same people who could serve as an early warning signal.

That tenuous balance has been tested again in what law enforcement authorities say is one of the most worrisome terrorism investigations in decades, the unfolding case against Denver shuttle bus driver Najibullah Zazi, who has been charged with conspiracy to unleash weapons of mass destruction in the form of hydrogen peroxide bombs.

A Queens man who had been a power broker in his Muslim community -- and a source for the New York City Police Department -- allegedly tipped off Zazi of the police interest early last month. That complicated the ongoing investigation of what investigators say were al-Qaeda operatives on American soil, and led to the indictment of the Queens man on criminal charges.
