Here is an example of this premise. South Korean authorities are currently holding a US soldier (unidentified, except that he is 20 and stationed at Camp Casey) on charges of attempted rape and robbery of an older South Korean couple, who ended up in the intensive care ward of a local hospital.
Having spent quite a bit of time in Korea, I can tell you that the younger generation in South Korea is not nearly as favorable to the US as are the older generations who remember the US' support during the Korean War and its immediate aftermath. This incident can't help the situation. Something tells me it would take an awful lot of diplomatic wrangling to get this soldier transferred to US custody.
