Ghost in the Wires by Kevin Mitnick

Decent but not as interesting as I'd hoped.

On Killing by Dave Grossman

A fantastic examination of how people kill, don't kill, and are trained to kill. Not flawless but very worthwhile. Main message: modern people mainly don't want to kill others, and when they do they suffer psychological consequences.

The Better Angels of Our Nature by Steven Pinker

A truly remarkable book. Highly Recommended

Violence is down ;)
