Today I had a customer order books by Malcolm X and Mumia Abu-Jamal, to be shipped to an incarcerated person. I regularly ship books to prisons, but I also know that some states consider possession of Black Panther lit to be equivalent to gang membership. I contacted the customer to let him know, in case he didn't. If the recipient had specifically requested these books, that would have been different, but they hadn't; they'd just asked for something to read.
