A bookstore with a single employee can no more verify the content of every new book or periodical put up for sale than Apple can verify all new content on the internet.
Books and periodicals come out far, far too quickly for an independently owned bookstore to read first. Never mind new books which have set release dates where bookstores might not get advanced copies for books sold on consignment.
If the owner stopped caring and just decided to let any book that passed through the automated "does this book immediately and actively harm the customer?" screening machine then you'd have something that approximates the app stores.

Enforcing anything other than that is a huge 1A violation IMO.
Phrasing this as "you" versus "a second party to the child" involves me, where I originally did not present a statement that would give the impression that I'd be involved. Keep me - "you" - out of it. I'm simply making fun of this analogy.
Correct analogies should be used to present the most fool proof argument.
