Turn them in or bear their sin

From The Washington Post 8/11/06

It all began with a tip: In the aftermath of the July 7, 2005, suicide bombings on London's transit system, British authorities received a call from a worried member of the Muslim community, reporting general suspicions about an acquaintance.
From that vague but vital piece of information, according to a senior European intelligence official, British authorities opened the investigation into what they said turned out to be a well-coordinated and long-planned plot to bomb multiple transatlantic flights heading toward the United States -- an assault designed to rival the scope and lethality of the Sept. 11, 2001, hijackings.

Note to the peaceful followers of Islam and the moderate members of the Arab community:
THIS is how you deal with the radical members of your society. TELL someone! We'll take it from there. If you give up these monsterous murderers, the rest of us will stop painting your community with the brushes of suspicion and hatred. Until that time, your silence gives consent and you have yourselves to blame for whatever happens.
