Shannen Rossmiller,35, and mother of three invites online terrorists by attaching her e-mail with video clips of Westerners getting their heads cut off.

"They get pumped up when they see beheadings. For them, it's like rock videos," Rossmiller said. "I always give the appearance that I am one of them."

She is a part-time paralegal and a $23,000-a-year municipal court judge in a town north of Montana.

Since the Sept. 11, 2001 attacks, she has found herself a night job. She uses the Internet to find terrorism suspects, she said.

Her husband, Randy, a wireless network technician, keeps eight computers and two broadband systems working in their house.

Posing as an al-Qaeda operative, she has helped federal agents set up stings that have caught two Americans -- a Washington state National Guardsman convicted in 2004 of attempted espionage, and a Pennsylvania man who prosecutors say was planning to blow up oil installations in the United States.
