The way things are now, I feel threatened in an airport. Especially a US airport, though Canadian ones aren't much better. I feel a heightened possibility that my valuables be stolen from me. That it's done under the color of law makes it even worse than being in a rough neighborhood.
Some may say this is unreasonable, but I know two people who've been stolen from by TSA.
I'd rather drive 8 hours than be subjected to a warrantless search.
Both alledged thefts were of jewelry in carry on, so if the allegations are true then it was TSA.
We are forced to divest ourselves of metalic objects and then put them through an xray, out of our sight, operated by a low class, unaccountable workforce.
Going through there gives me this mix of feelings: anxiety from being on my guard, fear that I may lose costly property, anger towards whose who designed this awful system and the liars who enable it, pity for the poor losers who work in it, and despair that Americans allow themselves to be treated this way - like chattel.
If that were the case, one could argue that the overpriced food at the airport also kills people.
As for your sources: The paper linked by Business Week doesn't say anything about the price of airport security deterring people, rather it is about the aggregate group that substituted driving for flying after 9/11, which has a myriad of causes. It does not support the assertion that the price of the TSA kills people.
The second link asserts that the time spent due to TSA procedures puts more people on the road, but I doubt this for two reasons: 1. security has been quick and efficient in my 2x-4x flights per year experience and 2. the rule of getting to the airport 1 hour before domestic and 2 hours before international flights existed before 9/11 too. So if somebody spends 30 minutes in a security line or 5 minutes, that affects their time twiddling their thumbs at the gate and not their travel time (and therefore doesn't really impact the decision to fly or drive).
