One of the biggest problems is not simply that there is a massive cover-up related to what is really going on at Fukushima; it is that the media itself is to blame for its lack of front page coverage of what is taking place at Fukushima as the situation has become even more critical.
Why? Because companies such as Japan's TEPCO filter which members of the press are allowed access to information and they filter the information itself. In the US, companies such as GE, owning media outlets such as NBC, are also in the nuclear technology services business. Bad press about nuclear is simply bad for business.
