These sound extremely interesting and are just about the only kind of books I'm into reading anymore.
I'll have to look for these the next time I'm at Borders, B&N, etc..
The internet may prove useful in findng these books. Liberty & Tyranny is new and at times completely sold out in stores. Death By Gun Control was published by a small gun rights advocacy group and never had a ton of copies made. Stores wont have it but ebay or amazon might. Really good book though.
