Let us, for the sake of argument, assume that any anti-terrorist restriction on travel will foil at least one terrorist action.
Is that enough to justify the restriction?
How many terrorist-caused deaths is too many? Is it one? Ten? Ten thousand?
I've never met anyone who liked it when I ask the question this way. Especially when I tell them that one is NOT too many, and neither, perhaps, is 10,000.
10,000 just happens to be one of the numbers bandied about in the immediate hours and days following 9/11 as a projected death count. It also just happens to be just about the entire population of the Iowa town in which I work and about 8 times the entire population of the town in which I sleep.
My question is this: One of you is a bacterium that, if you are allowed to stay free, are going to take out 8 towns like the one I live in (including mine). Not might take out. Will take out. No uncertainty at all. You're out there. And if you're not stopped, I and 9999 others are going to die.
But the rest of you, all 300-odd million of you --you're going to be just fine. Regardless of whether the bacterium does its evil or not. Regardless of whether I die or not.
So, should I be able to have all of you be scanned to make sure you're not the bacterium?
Personally, I don't think the answer is obviously "yes" in this case of 10000 "certain" deaths. And it is even less obviously "yes" in the real world of uncertainty. Do we really need to protect each other against every 1 in 30,000 risk of death out there?
And do not be conformed to this world, but be transformed by the renewing of your mind, that you may prove what is that good and acceptable and perfect will of God.
