Picked up and finished Fast and Furious – as suggested by Joe; short book, especially for someone that’s been following along since the beginning. The nicest part of the book, for me, was the timeline in the appendix; the writing was workmanlike, as one would expect in a straight true crime writeup.
If you’ve been keeping up, the book is completely review; purchase it to support the author. If aren’t read up, or are only vaguely aware that there is a gunwalking scandal, you should read the book to get up to speed. Why the Mexican government isn’t raising a big stink is obvious – a half-billion dollar payoff. Why Congress isn’t raising more of a stink is less obvious, but it’s early days yet.
