Foreword by Timothy J. Mullin, of ''Unintended Consequences.''Since the 2002 edition, over 200 pages of various revisions have been included during the annual reprintings. Amazon carries the latest 2009-on printings which include Boston's several page analysis of the Heller decision. (This is not some completely new edition, as some reviewers have incorrectly inferred. Three-fourths of the book remain the original text of 2002. The other fourth are revised pages from 2003-2009.)While Boston recognizes that gun/gear prices have changed, and that a few new worthy products have emerged, he does not feel that the title yet deserves a completely revamped edition. Good basics never change, and BGB is pretty thorough about those.
