Turn on those captions!
San Francisco is considering a law that would require TVs in public locations (lobbies, restaurants, airports, etc.) to display captions at all times. What a great idea, and why not? The capability is already built in, and this would provide a robust channel for communicating with deaf and hard of hearing people about emergencies, at the very least. But don’t fine the scofflaws; make them wear a scarlet ASL instead!
