What about my privacy?
ShotSpotter is committed to preserving privacy rights. ShotSpotter systems do not trigger on human speech or other non-threatening sounds. Furthermore, our sensors render human speech unintelligible at distances greater than 20 feet away from our sensors, and therefore even if someone were to be speaking coincidentally at the same time as a gunshot is detected (hence triggering the system), the system would likely only record the sound of the voice, while the words themselves would remain garbled. What about people standing less than 20 feet away from the sensor? Remember that ShotSpotter sensors are deployed on rooftops, telephone poles or in other restricted-access locations. Locations are specifically chosen to avoid the possibility of people or conversations being overheard.
Isn?t this ?Big Brother??
With all due respect to Mr. Orwell, gunshot location systems are not intended or used to spy on our citizens. (See the answer immediately preceding for details on how ShotSpotter does not trigger on noises which do not sound like gunfire.) In cities in which ShotSpotter is deployed, it is illegal to discharge a firearm except on a certified shooting range or under other controlled circumstances. Thus, anyone who does fire a gun has broken the law, and it is our position?with which district attorneys, police and civil rights groups agree?that firing a weapon illegally within city limits creates a significant threat to public safety and therefore warrants the detection of the event, investigation of its perpetrators, and possible indictment of suspects.
