I will feel so much more safe knowing that this is available. Can't wait until the world is wired with this.

Microphones around the city; hummmm, can it record voices too? Or did I jump to far into tin foil?

Technology has been around for a while and already in use in some cities. I don't see the point in dumping that much money into it, but I also don't understand why we need cameras at every intersection with stop lights either. Too much government waste.

Yup, been around a long time. Mostly in large metro areas. There is other technology they use on us that makes this look like a pop gun in an old west shoot out.

Indeed, the technology has been around for awhile. Has been installed in several metro areas. Guess what the real success rate - ie., arrests - is? Zipola.

Money would be better spent keeping criminals off the streets.

20% of the time a gun is fired in the US, 911 is called. the other 80% of the time no one calls 911".

He's not even close with those numbers I suspect. Maybe he only means 20% of the time in his city, but all of the US, no way is that number even mildly close. I watched a show that used to be on that highlighted in technology being used by the army. They had a "fired shot" detector mounted on top of a Humvee that showed the occupants which direction gun fire was coming from. It's was pretty cool, since you would have a hard time hearing the gun report while in the vehicle. This allowed them to direct their gunner to the right direction to return fire. THAT was a good spot for this tech. to be used.
