Moments later, he texted again. “Call them mommy. Now. He’s coming,” he wrote. Justice, who would later be confirmed among the 49 people killed in last month’s attack, was among several victims who texted relatives to call 911, fearing they would draw too much attention by making voice calls. None of them could text 911 directly because Orlando is among the vast majority of US cities that do not have that capability, but as shooter and hostage situations become more common, police departments are exploring technology that would allow dispatchers to receive texts, photographs and videos in real time. Out of more than 6,000 dispatch centers nationwide, a little more than 650 can accept text messages, with more than 150 making the text-to-911 upgrade this year, the US Federal Communications Commission said.
US Senator Charles Schumer has been pushing for text-to-911 in New York City, which has been studying it for nearly a year. Such a system, he said, can “save lives by informing 911 dispatchers of critical details that can guide first responders.” However, emergency officials stress that a voice 911 call is preferred when possible because a dispatcher can elicit details more quickly than texting back and forth. The major concern for many cities, including some of the nation’s largest, is that overuse of texting when it is not absolutely necessary could slow response times and cost lives. In Los Angeles, which does not have 911 texting, a police dispatch official last year cautioned that response times for text 911 could be triple that for voice calls. Nearly every municipality with the text-to-911 service has sought to address that concern by promoting the slogan: “Call if you can, text if you can’t.”
Officials also warn that with text messages your approximate location is not automatically sent to emergency responders, like it is with voice calls. Instead, they encourage people to give 911 call takers an accurate address or location as quickly as possible. Supporters of such systems say their use would go beyond shooter and hostage situations to scenarios in which a battered spouse, for example, could surreptitiously message police without alerting the attacker. “If someone could snap a photo or a quick video showing the perpetrator that’d be enormously helpful to law enforcement,” said Joseph Giacalone, a criminal justice professor at John Jay College of Criminal Justice and a retired police detective.
San Bernardino, California, rolled out its text-to-911 service in December last year about two weeks after an attack at a social services center where a man and his wife killed 14 people. In New Hampshire, where the text-to-911 service is available statewide, Governor Maggie Hassan said it was a “common-sense initiative that will help save lives.” Authorities say 911 texting, like its telephone counterpart, has also been abused. Last year, a teenage girl texted 911 to falsely report there was an active shooter at a high school in Marietta, Georgia. Police arrested her at her home an hour later.
