I am left to wonder whether my own passive acceptance of these evolving search procedures has contributed to a potentially fatal dichotomy: what we allow TSA screeners to do in order to maximize efficiency and enhance our perception of safety, or what we really need them to do in order to preserve our rights and dignity and enhance our actual safety.

We have asked TSA to find the tools terrorists use and prevent both from boarding a passenger plane. We have unintentionally created an agency that now seeks efficiency and compliance more than any weapon or explosive.

While returning my computer and shoes to their proper places, I watched the screening line at BWI. I thought about the haphazard events surrounding the security screening process. As I watched the screening officers, I wondered what information drives their decisions. Left only to my observations, I concluded that their decisions were entirely random, and likely based upon three criteria: passenger load, staffing, and whim.

I was left to conclude that I am not screened because I look like a terrorist. I am routinely screened because I look like someone who will readily comply. I decided then that my next invitation to enjoy additional screening would be met with more inquiry.

With the economy slowly rebounding, 2011 was shaping up to be the best year for travel since the recession began. Prices were expected to rise only slightly, and people were making plans to take a long-postponed vacation.

But now that the Transportation Security Administration has introduced full-body scanners at many American airports, and subjected those who opt out of the machines to an "enhanced" pat-down, the 2011 outlook has changed, say travelers.
