You can download a similar book for free in PDF format. John Ross' "Unintended Consequences". I've converted it to the proper format so I can read it on my Kindle. :) Although I have a hard copy, bought from the Texas State Rifle Association when it had not been out all that long. It's a big book, the Kindle is much smaller and easier to carry around. More stealthy too when you are reading politically incorrect books. ;)
Turns out it's also available in other formats, including Kindle's mobi. http://www.ebook3000.com/ipad-iphone/Unintended-Consequences---John-Ross_127434.html
