If a suicidal maniac jumps suddenly into the path of your oncoming car and you hit him/her,the law instantly considers you guilty .
It does not matter whether the pedestrian was totally drunk,a jajuok (night runner),plain careless,sick,whatever - hiyo itabaki ni story. If the guy dies,straightaway you get slapped with a manslaughter rap.
..there's nothing,absolutely nothing really,that I can't do if I put my mind to it.
