Good mod, though I would have hidden it in the Georgetown Police Station, since certain unique weapons require killing a lot of hostile NPCs to get to them (feral ghouls for Lincoln's Repeater, army of raiders for the Terrible Shotgun, hordes of Super Mutants for Eugene, etc) and the Georgetown Police Station is overrun with super mutants. Plus, the name of the gun implies it has a police-related origin. It would also be a reward for doing the Big Town rescue mission. It could be in a safe unlocked by a computer or next to a skeleton in a locked closet.
