Don't get me wrong, I'm all for pursuing any person who behaves as in the article to the greatest extent possible, but you they have to get IP, dig up the person, contact authorities in that country and hope they do something?
That's a lot of paperwork for maybe something _might_ be done and no one died and no large amount of money went missing (so to speak).
Maybe it's not so much they don't care (most people would care about this no?) and more they are limited in resources (and perhaps motivation) and it is difficult to get results.
