Seems like the problem could be almost totally solved by a significant reduction of 911 calls by (1) Enforce laws against misuse of the system (non-emergencies, hoaxes) (2) Support technology that allows quick texting to 911, adding in a filter that recognizes multiple calls for the same event (nothing is gained with 10 calls for the same non-emergency auto accident). By using texting technology, you could eliminate a lot of the time-consuming back and forth between a human operator. If you listen to recordings of 911 calls, they are almost always incredibly time-inefficient because callers are hysterical and/or irrational.
