Heard on the subway earlier today “Ladies and gentlemen. A crowded subway is no defence to unlawful sexual conduct. If you believe that you have been the victim of a crime, or witness to a crime, notify an MTA employee or police officer.” That’s a new one on me, but I looked it up and it’s been around since 2011, part of the MTA’s “If you see something, say something,” campaign. Not sure I’ve ever heard anything similar on the London Underground.
