(The position advocated by that brief was accepted by a minority of the court; the majority ruled in our favor for a different reason, based on the physical trespass against a person's car when attaching a tracking device to it.)
But then the original article about Easton mentions him having received an award as part of the 'GPS team'.
Truth is, projects the size of GPS spanning that many disciplines will have dozens of people that rightfully can be called father of (parts of) the whole. And while some minions might have been easily replaced, a few grest minds will have significantly advanced their field of research while making the project fly.
EDIT: Glad to see someone of this bent taking a legislative seat.
