" Whatever it is we are trying to find out about the strangers in our midst is not robust. The “truth” about Amanda Knox or Jerry Sandusky or KSM is not some hard and shiny object that can be extracted if only we dig deep enough and look hard enough. The thing we want to learn about a stranger is fragile. If we tread carelessly, it will crumple under our feet. And from that follows a second cautionary note: we need to accept that the search to understand a stranger has real limits. We will never know the whole truth. We have to be satisfied with something short of that. The right way to talk to strangers is with caution and humility. How many of the crises and controversies I have described would have been prevented had we taken those lessons to heart? "
