People can livestream their every move on Facebook and chatter endlessly in group chats. But in most parts of the US, they still can't reach 911 by texting – an especially important service during mass shootings and other catastrophes when a phone call could place someone in danger.
Although text-to-911 service is slowly expanding, the emphasis there is on "slow." Limited funds, piecemeal adoption and outdated call-center technology have all helped stymie growth. Emergency 911 centers stress that a phone call is still the best way to reach them, since calls provide them with location data and other needed details.
