The website seems to be gone now, but it was a simple form that submitted a Freedom of Information Act request to the Department of Homeland Security. I'd never requested anything under FOIA before, and my personal history seemed like a place to start. I thought it was a good exercise, both as an information professional and as a private citizen.
So I was happy when, earlier this week (almost exactly one year later), I received a letter from the US Customs and Border Protection saying,
A search was conducted of the [Automated Targeting System] database, and we were unable to locate or identify any responsive records.
Which means I am flying under their radar (until this request, probably).
Not that I thought there would be anything untoward in my flying patterns, but these days, you never know. Now all I need to do is take my official "he's no terrorist" letter to the nearest TSA worker for a smiley face.
