I was honestly unsure about this book going in--having read other true crime (and non-true crime) by people in the justice system, there can be enormous ego, bitchiness, one-sidedness, and just bad writing.
Happily, this book was the opposite. Porter presents everyone (except, of course, the killer) in a positive light. He explains a variety of things in detail: ballistics, jury selection, why the defense can do things prosecutors cannot (and why this is instrumental for our democracy), and much more. He also goes into how gun violence and the lack of a good understanding mental illness are affecting this country.
I would have appreciated more on the victims--I never really got to know them--but that is my only criticism. The crime itself is very timely, given the state of people's paranoia/anger/distrust/blaming of everyone else we are currently experiencing.
A must-read for those interested in true crime and/or the law.
