Query: a really sad look at a preventable disaster

What's so sad and disturbing about this book is that it's full of excuses by the author. Williams contends, ludicrously, that people at Galeras had to die in order to advance science. These types of cover-ups do an incredible disservice to the scientific community and seek to pull the wool over the eyes of the general public. Williams denies having any guilt, even though he was the leader of an expedition that took a group of mostly inexperienced people into a volcano: "there is no guilt," he writes "there was only an eruption." What I read into this, was that Williams is indeed guilty and his unending protests that he did nothing wrong (very similar to some characters in the news over the past few years) are obvious cover-ups. It really left me with an incredibly bad taste in my mouth and absolutely no respect for this man who calls himself a scientist, but doesn't even have the heart to admit that mistakes he made cost people their lives.
