Question: This is a great book so far. I am a little farther than halfway into it and it is great. Although the writing is a little choppy at times, it is definitely worth it.

Answer: Positive

Question: I am using this textbook in a class and it is a whopper. Wonderful pictures, easy to read, clear colors and understandable. I've been working in prisons for 5 years and this book makes a lot of sense. You ought to read their sections on women in prison and on probation. I loved the parts on geriatric prisoners (old cons) and the death penalty. And it is easy to read. More!

Answer: Positive

Question: I thought this was a terriable book by itself, but makes for a nice companion when reading through McQuarrie's book. McQuarrie skimps out on some of the explanations and instead leaves it to the reader to figure it out for themselves by solving his problems at the end of the chapter. One can usually find the answers (or at least some hints) within this book.

Answer:
Negative
