According to stsistics I pulled from Google, 2 billion passengers fly commercially each year.  Conservatively, I'd estimate that the excessive security measures implemented since 9-11 cost each of those people an average of at least 15 minutes.  So 500,000,000 hours of human life are wasted each year on these security measures (side issue: have they ever caught any terrorists?)

The average human life lasts 700,000 hours.  So we're wasting 714 human lives each year.  Since 9-11 we've wasted over 7000 human lifetimes on this stuff.  More than twice as many lives as were lost in the attack that day.

And we're doing it to ourselves.  They surely are getting a laugh out of this.
