Query: What a Waste of Time!

Wow, all I can say about this book is that it was very amusing. I have never in my life read a book that contained so many grammatical errors. I felt that this book was a waste of paper. Everything that Murphy said was completely irrelevant to the topic of Columbine. The book could have easily been condensed into a much shorter piece. The majority of the statements made by Murphy did not make sense at all. Overall, I felt that the book was a waste of my time and a waste of Murphy's as well.
