I just found this Seattle Times article linked to on Jihad Watch.

When it's 4 a.m. in this one-stoplight prairie town, it's 3 p.m. in, say, Karachi, Pakistan, the sweltering hours just before the evening call to prayer. That's when [Shannen] Rossmiller, while her husband and three children sleep, finds the Internet chat rooms and bulletin boards frequented by radical Muslims and jihad warriors are busiest.

Mrs Rosmiller is a cyberspy, who advises the FBI when she finds something amiss.

So it was that, on one of Rossmiller's trawls through Web sites with names like bravemuslim.com last fall, she came across a posting by a man calling himself Amir Abdul Rashid. It was clear from the message that Rashid was edging toward the violent fringes of Islam.

Over time, it also became apparent to her that he was an American soldier.

Posing as an Algerian with ties to that country's outlawed Armed Islamic Group, she sent Rashid an e-mail with the subject line "A Call to Jihad." Rashid responded by asking if it was possible that a "brother fighting on the wrong side could defect."

Over a period of four months, Rossmiller drew out Rashid through a series of 27 e-mails. She learned, with growing alarm, that he was a National Guardsman about to be deployed to Iraq. And he appeared willing to share information on American troop vulnerabilities with the enemy. Rossmiller provided the information to the Department of Homeland Security, which passed it to the FBI and the Army.

The arrest in that case of Ryan Anderson, 26, a troubled Muslim convert and a specialist in the Washington state National Guard's 81st Armor Brigade, was splashed across the country's newspapers in February. It was a direct result of Rossmiller's work, and she is expected to be the reluctant star witness at his pending court martial. She testified in a preliminary hearing last month.

Rossmiller, 34, was born and raised in Conrad, her father a farmer and her mother a special-education teacher. A former high-school cheerleader and honors student, she now draws on her legal-research skills in her quest.

Rossmiller says there is no mystery to how and why she developed her avocation. It traces to Tuesday morning, Sept. 11, 2001.

We should all be doing this. Who's willing to make a pledge to trawl the anti-American Jihad websites and chatrooms, hunting out the enemy? I will start tonight. Further information can be found at 7Seas, an amatuer sleuthing organization formed shortly after 9/11.
