Fatal Vision: A True Crime Classic

okay so this book took me way too long to read for a true crime lover.. it just was so dry and by the end of it I don't know who I was more pissed at the author Jeff or the government.
What it comes down to is this (and I can't figure out how MacDonald's supporters downplay this): the guy was a Green Beret. His family was brutally slaughtered and he had minor wounds. Was he a complete and utter wimp who was physically unable to protect his wife and children (something I can't believe) or was he himself guilty of the killings? This book gives good background on the evidence used to indict and convict the pathological, narcissistic nobody, Jeffrey MacDonald.
