Wikileaks, Nothing New - except the DNA stuff

I'm still not astounded at anything in the diplomatic chatter released by Wikileaks.  It is not surprising that elements of China's leadership think that North Korea 1) behaves like a child; 2) needs to be brought under control and (least surprising of all) 3) believes that the Korean peninsula would be better off unified by the South.  It is also not surprising that most Arabs would prefer to see Persians vanish.  All this is a BGO - blinding grasp of the obvious.

What is surprising is why US State Department officials would want their diplomats to acquire DNA and other biometric data on foreigners. Not to mention how they were to go about it.
