It's pretty clear, though, that Jarrod Gilbert has enjoyed hanging out with gang members rather more than Hager would. Gilbert's affection for his scruffy, big-boned subjects is barely contained.
This is a darned good read and the author knows it. No need for an effusive guest foreword; Jarrod wrote a perfectly glowing preface to the book all by himself.
This is followed by 280 pages of detailed description of the New Zealand bikie and street-gang scene. Accompanying press photos reproduced with great care on high-quality paper are a particularly well-executed feature of the book.
A minor disappointment is Jarrod's investigation of Asian gangs, which seems glossed over, with little original material presented, as if the author is less interested; he might better have kept to the patch-wearing gangsters of his title.
The conclusion of the book is logical and carries the authority of a dedicated researcher who has risked a great deal in his pursuit of knowledge: attacking gangs strengthens them. Grandstanding law-and-order politicians should take note.
