At the center of the uproar over a Google project that scooped up personal data from potentially millions of unsuspecting people is the company software engineer who wrote the code. Google has declined to identify the engineer, as has the Federal Communications Commission. The agency also said it was unable to resolve all the issues it was considering because the engineer - whom it referred to in its report on the inquiry as Engineer Doe - cited his Fifth Amendment right and declined to talk. Now a former state investigator involved in another inquiry into Street View has identified Engineer Doe as Marius Milner, a programmer with a background in telecommunications.
