have you seen this article as a crime stopper?

i'm thinking it works like sonar measuring doppler shift as well as time to strike a sensor (with comparison of the signal to prevent multiple gunfiring in an area as to throw the search area off as can happen in HF rescue by radio triangulation)
what are your thoughts on the technology and do you think it could not be used effectively to get police on scene in a hurry.
also give me your opinion of crime stoppers where crime can increasingly be mapped out to weapons other than guns... thanks in advance
More than likely, I'm guessing, the sensors are just microphones and they are connected to a computer that determines which microphone picks up the sound of a shot first. Then it triangulates based on subsequent detection by other microphones. They might even be able to detect the intensity of the sound to help make the determination.
It sounds like a pretty good idea for areas where there is a high incidence of gun violence. But of course you have to have enough cops to be around to respond to the alert when it comes. So as usual, it requires a human element to be provided for.
The technology for detecting crime due to the use of weapons has to be based on the type of weapon. I think it's going to be fairly hard to develop something to detect the use of an edged weapon (think knives and cutting weapons) or anything that doesn't make much noise. Any such detection device is likely to be so sensitive that it could be used for nefarious purposes and be declared illegal rather rapidly.
If you start talking about property crimes where the sounds of break-ins are made, alot of burglar alarms already employ detection devices for that. So some devices already exist.
But wouldn't it be nice to have a device that instantly detects a crime occurring? Sounds real Big Brother to me and we'd have more trouble than trying to detect crime.
