Sigh, the 5th Amendment ... I find it distressing that as a result of Kelo I agree with JJ. Scalia & Thomas on something. (Am I the only one who keeps hearing Cole Porter's "Anything Goes" -- good's bad today, and black's white today, and day's night today -- in her head these days?)

Anyway, on the 4th I agree with your concerns about how random those "random" searches will be, and wonder why random searches are more acceptable than those based on a Terry or equivalent suspicion. I think someone on the news last night admitted that they'd be focusing more on folks with bigger bags -- as a practical matter that makes sense, but then it's not truly random.... And I don't think the DWI/roadblock system of just searching every third or tenth (or whatever) person would work ... everybody would immediately try to game that system somehow.
