Re: Hmmm
They've already worked out how to call 999/911 on a phone. I can see why texting them might be useful - if you were hiding in your closet with an intruder already in your home it would allow you to silently call for help. But even that I think is unnecessary - calling 911 in the US and saying nothing works...they'll send police/ambulance over since they assume you're in distress.
But why the fuck would anyone tweet that they need help? What would happen is that idiots from 4chan would delight in sending tweets asking for help using hacked PCs (for the geolocation information, and to hide their identity) so it would have about a 99.99% false positive rate. Much harder to spoof a phone call, whether landline or cell.
