Amazon has banned a book that provided the code to create a 3D printed gun.
The book, a 584-page tome called The Liberator Code Book: An Exercise in the Freedom of Speech , contained computer code that could reportedly be fed to a 3D
printer to create a plastic gun called The Liberator. The book was selling at $20 prior to being removed from the store

The purpose of this exercise is to give a physical analogy
between computer code and books. Code is speech. This is a printed copy of .step files for the Liberator. and not much else. Don't expect a gripping narrative: that's being played out in the news and the courts. Proceeds from this book will be used to
fight for free speech and the right to keep and bear arms.
According to The Washington Post, the book had appeared on Amazon on August 1, just a day after a federal judge had issued a temporary restraining order, blocking the public
availability of the code in question.
Amazon took down the listing noting that it violated Amazon's content guidelines, but would not elaborate further.
