>"[I]f tomorrow air passengers were offered the option of a 'secure' flight on which all passengers are subject to security, or a 'non-secure' one where they could go straight to boarding, hassle-free," he writes, "I promise you that many travellers would still take the 'secure' option."

I would take the "secure" option because who is left taking the "non-secure" option? Terrorists.

If all the flights were "non-secure", just like every train ride, then we spread the terrorists out and my odds are better.
