YO SAM KATZ, I’M FLYING TO CHICAGO NEXT WEEK!!! FYI. BE HOME BEFORE CURFEW!

Comments as debate rules. Here are some articles supporting the Invasion of Privacy theory RE: CAPPS II, the passenger risk-assessment givin’ it all up at the airport thing.

Here, two MIT students (god love the MIT students) apply an algorithm to calculate CAPPS I and disprove its safety, not to mention legality under the 4th Amendment. Did I mention I love the MIT students? I love the MIT students. Here’s an interpretation of the MIT paper by a non-MIT student.
There are lots more links here, where I got the first two.
