Amherst man’s gun permit reinstated after error – David A. Lewis, a college librarian from Amherst, got his pistol permit reinstated Thursday and is getting his seven guns back soon, but not before touching off a new round of debate over Gov. Andrew M. Cuomo’s NY SAFE Act.  Somewhere between the State Police in Albany and the Erie County Clerk’s Office in Buffalo, the wrong David Lewis lost his gun permit and his handguns.
