I don't really know police procedure but I've watched a lot of Law and Order. One thing I recall is fights over jurisdiction. You know, the feds withholding info from the cops and suchlike. Here, the Coast Guard are involved, which is mostly unsurprising when you consider the Korean name 'Sea Police'. More surprising is the involvement of Pohang police. I think the missing coastie, named Kwan, is from Pohang or he was out with a group from Pohang, but anyway, Sokcho seems like a reach to me.
