After the contraband came the suspect: a bespectacled woman, with a T-shirt printed “I am a bookstore employee”. The raid on “Have a Nice Stay”, a bookstore in Hong Kong’s trendy Mong Kok district, on July 15th was part of the Hong Kong government’s campaign against retailers of the printed word. Outside the half-closed shutter of the nearby Greenfield bookstore, two plainclothes police officers brusquely told your correspondent to shove off. The day before the raids “Have a Nice Stay” said it was closing, as it could not navigate the government’s “unclear red lines”. The police’s enormous haul suggests they might not know where the lines are either.
