You have missed the point.
This is about the PERSONAL DATA of those who, as far as we know, are NOT EVEN PERTINENT TO THE CASE being made public. NK's "friend" Jeff, whoever he is, and as far as we are currently privy too, has already been tracked down.
Now, if this guy is just a friend, and has NO BEARING ON THE CASE, and is not a witness, but is just some guy who happened to know NK - why is his personal data released??
That has NOTHING to do with the gov't. being beholding to the public. Zero.
