Faisal Shahzad

TPM has a profile of Faisal Shahzad Times Square Bomb Suspect Jogged, Slammed Bush, Defaulted On Mortgage.

"That portrait, compiled based on accounts in several news outlets, is notable for the way in which Shahzad -- like so many of the young men behind Islamic terror attacks on the U.S. and Europe -- seems to have been simultaneously alien from, and embedded within, western culture. Born in Pakistan's remote and tribal Northwest Frontier Province, Shahzad, 30, grew up in a country that banned alcohol and taught Islam in school, and he maintained close ties to family members in the region. But he also went jogging in his suburban Connecticut neighborhood, and perused used car websites to find the Nissan Pathfinder that he's charged with using in the bomb plot. And he seems to have gone over the edge not long after participating in that archetypal American ritual of recent years -- defaulting on a low down-payment mortgage."

There are details but not of the interesting parts. Why did he default on the mortgage (did he lose his job)? What inspired the plot? What was the purpose of the plot?
