> Why were none of the Japanese executives arrested? For what? A criminal is claiming his innocence, classical story, people do that all the time. Without further proof, why should anyone bother people who are probably innocent, and more important: powerful. That could seriously harm your career if you do something to lightly. Who would do that in this situation? The other problem is the pretty strict chain of responsability people in Japan maintain. Especially in the legal system, there is a very strong and infamous believe that people do not fail in their work, and questioning it is a serious matter. This is a long known problem with japan, but it's quite hard to fix this. So even in a regular harmless case, hardly anyone would do something to insult someone else by questioning the result of their work.
