The Dakota / Reacher's name origin

The Dakota

For some, the Dakota is the creepy apartment building in Roman Polanski's chilling film Rosemary’s Baby. Polanski envisioned a Dakota where residents were all members of a devil-worshipping cult trying to get a young Mia Farrow pregnant with Satan's child. For others, the Dakota is the place where John Lennon lived and died. In a chilling real-life turn of events, Lennon was shot and killed across the street from his home at the Dakota on December 8, 1980.

It is also one of the locations in "The Hard Way."
How Jack Reacher's name was chosen, according to the author.
