Security Spending and ROI

I read an article by Bruce Schneier called Security ROI in CSO magazine.
Here is an excerpt from it:
“Assume that all the new airport security measures increase the waiting time at airports by — and I’m making this up — 30 minutes per passenger. There were 760 million passenger boardings in the United States in 2007. This means that the extra waiting time at airports has cost us a collective 43,000 years of extra waiting time. Assume a 70-year life expectancy, and the increased waiting time has “killed” 620 people per year — 930 if you calculate the numbers based on 16 hours of awake time per day. So the question is: If I did away with increased airport security, would the result be more people dead from terrorism or fewer?”
I thought, what an interesting way of looking at this. Now take this creative tidbit with the knowledge that his point in the article is that the ROI calculations performed by companies to validate security products they sell are bogus and highly biased. Read the entire article. I recommend it.
