Very special thanks to my wife, retired Sacramento Police Department Narcotics lieutenant Diane Joelson Brown, for her encouragement, support, and technical advice. This book would not have been possible without her patience, insight, and expertise. The mistakes are all mine, but the credit goes to her.
Thanks also to Lieutenant John Kane, disaster-preparedness expert, Sacramento Police Department; Lieutenant Leslie Brown, watch commander, North Patrol, Sacramento County Sheriff’s Department; Detective David Cropp, Narcotics investigator and expert, Sacramento Police Department; and Officer Vonda Walker and Corporal Paula Gow, Sacramento Police Department, for their technical assistance.
I also thank retired Sacramento Police Department officer and fellow pilot Bert Sousa for his help in profiling and helping to gather information on outlaw motorcycle gangs. A source of information on biker gangs, which Bert encouraged the author Yves Lavigne to write, was Hells Angels: Into the Abyss (New York: HarperCollins Publishers, 1996). Hells Angels is a registered trademark of the Hells Angels Motorcycle Corp.
