Sam Harris and Bruce Schneier Debate Airport Profiling | Samharris.org
It is still not clear to me what you actually recommend—nor is it clear why your views about profiling, if true, wouldn’t extend to all intelligence work, or even to immigration. Should we issue visas to people at random, or should we pay more attention to those applying from Yemen, Pakistan, and Somalia? For those seeking to immigrate from Canada, should we give more scrutiny to Arabs or to Inuit? I don’t see how you can pull the brakes once this train has left the station. The base rate of terrorism is low everywhere and on all occasions. And, yes, we have an ethical commitment to treating people fairly, wherever possible. But it seems to me that you have made far too much of these facts at the airport—and, given your reasoning, they should vitiate our commitment to targeted security on every other front. Rather than fly drones over Yemen, we should let them drift with the wind and rain down missiles at random.
I think this was a brilliant debate. I would have to fully parse Schneier's main points before I could truly know how strong they are, but have seen actual flaws in more than one of them. Sam's point, however, seems overwhelmingly strong but without a solid implementation route.
One thing is for certain: profiling combined with random screening is the best combination. The question is simply whether or not any profiling system can be implemented that will increase security more than it will cost (in various ways).
That wasn't answered here, but I think Harris definitely won the argument of whether profiling could help, while Schneier won the argument of it not being as simple as, "Look for Muslims."
Luckily for Sam, that wasn't his argument, although Schneier seems towards the end to wish it was.
