Terrorists becoming harder to profile

As reported by the Washington Post, terrorists are becoming more and more difficult to profile. The statement, though, begs a question:

I think the only constant characteristic of terrorists is that they all tend to be pretty pissed off. Maybe we could start there?

The article provides several examples showing why profiling people to discover the "evil doers" is such a ridiculous idea:

In neighboring Belgium, people are still perplexed over what drove Muriel Degauque, 38, a blond, white Catholic, to convert to Islam and travel to Iraq to blow herself up in November 2005. Nizar Trabelsi, convicted two years earlier of plotting to bomb a NATO base in Belgium, had been a European soccer star before going to Afghanistan to attend al-Qaeda training camps.

In Britain, three of the suspects arrested in last summer's alleged transatlantic airline hijacking plot were religious converts who grew up in north London's affluent suburbs. One was the well-to-do English son of a Conservative Party activist; he worked in a bar and loved the movie "Team America."
