The manhunt continues for Christopher Dorner, the former Los Angeles police officer accused of killing three people in California. The Los Angeles Police Department has promised a $1 million reward for leads on Dorner's whereabouts. But conducting a wide-scale manhunt for a potentially dangerous fugitive has its complications.   This past weekend Darrell Satzman, producer at KCRW in Los Angeles,   came home with his young family to find plainclothes police officers on his front patio. The cops had pistols strapped to their legs and were wielding shotguns.   It turned out that an L.A.P.D. member who lived in Satzman's neighborhood had been named as potential target in Dorner's manifesto. Mendocino County Sheriff Tom Allman is also familiar with just how difficult a large-scale manhunt can be. Sheriff Allman is the co-author of "Out There in the Woods: The Day-by-Day Account of the Extraordinary 36-Day Manhunt for a Double-Murderer on the Northern California Coast." based on a 2011 search led by his team. Sheriff Allman describes his experiences – and explains why he has offered Mendocino County's services to the L.A.P.D. to help them track down Dorner.
