Why do so many feel this is exceptionally barbaric?
More like exceptionally emotional. Really, I'm not trying to start an argument, but this tangent seems both off-topic and unappreciative of the fact that no country (AFAIK) is obligated to permit foreign visitors. That said, to the extent the US can encourage well intentioned, law abiding foreigners to visit, I believe that it significantly adds to the culture, economy and general health of the society. Besides, isn't the information exposed by a fingerprint a far cry from that exposed by DNA?
