That sounds like it could be a useful tool! I am not sure how I feel about it, though.
There have been times when I texted a friend to call for me, because I didn't want to call (pumping gas and a crazy fight broke out, or drug deal going on) and be overheard calling the cops on them. It sounds like a lot of work for dispatchers, and a lot of stuff to sort through to get life saving information. A lot of times people are pretty frantic, and the dispatchers use their skills to calm the person down. I wonder how that would work in a text? I hope it doesn't lead to more false reports/ prank calls. I also hope that they are prepared for potential delay in service type accusations, while they try to sort out the text messages.
