Schneier Has Something Good To Say About Airport Security 226
Bruce Schneier points out on his blog a proposal to use electronic randomizers at airport security checkpoints. Schneier writes there:
"I've seen something like this at customs in, I think, India. Every passenger walks up to a kiosk and presses a button. If the green light turns on, he walks through. If the red light turns on, his bags get searched. Presumably the customs officials can set the search percentage.
Automatic randomized screening is a good idea. It's free from bias or profiling. It can't be gamed. These both make it more secure. Note that this is just an RFI from the TSA. An actual program might be years away, and it might not be implemented well. But it's certainly a start."
In this case, the proposal is for randomizers that direct passengers to particular conveyor-belt lines for screening.

Yes but if it's random surely they would need a separate belt for the foreign looking people thats more random.. Right?

Any terrorist with a simple grasp of binomial theory could work out the number of terrorists to send through the gate necessary to achieve a 90% confidence that one of them gets through with the bomb, given only the relative probability of red vs. green.
So we must prevent binomial theory getting in the hands of terrorists.

Issue the TSA some dice?
Only if I can negate the search with a saving throw...

And don't forget the advanced adaptive screening rate through combinatorial probabilistics with both parallell and serial execution methods. You can also implement multiple selection criteria at once, subselecting some passengers to even more intensive screening methods. Though for expediency I'd recommend the d20.system instead.

I propose we read a TSA einsatzgruppen's entrails then ignore the results and repeat until we're happy with the answer.
