And these are your cites for to back up the statement that there are systems
in place in all metro areas to triangulate gunshots? THey are, on the other
hand, pretty damn good cites to prove you were wrong since they all are
talking about a pilot program taking place in a few high crime locations in
a couple of cities.

So the request is still out there. Do you have any cite for your theory
that
there are microphones scattered over metro areas to triangulate gunshots?

Police cams to add gunshot detectors

by Fran Spielman, City Hall Reporter
Chicago Sun-Times

Chicago - Big Brother isn't just watching the bad guys in Chicago. By
late summer, he'll be listening as well -- for the sound of gunshots.

Gunshot detection technology -- capable of "triangulating within 20
feet" the location of a shooting -- is being added to 30 surveillance
cameras already in place on high-crime corners and to 50 new cameras
expected to be installed by late summer at undisclosed locations.

Waiting for the Gun
A USC engineer uses his expertise with nerve cells to create a
surveillance system that can recognize the sound of a nearby gunshot -
and identify the shooter. In a unique pilot program, L.A. and Chicago
will deploy test units in high-crime areas.

Until recently, the Los Angeles Sheriff's Department
(LASD) had no idea how many incidents of actual
gunfire occurred near its Century Station, one of the highest
crime areas in Los Angeles County. Some were random
shots fired into the air; others were drive-by shootings.
Some were nothing more than firecrackers or backfiring
cars. Either way, the majority went unreported.
But a new technology may make this lack of reporting a
thing of the past. Although still in the experimental phase,
gunshot detection technologies are showing promise as a
new way to detect and pinpoint the location of gunfire.
Based on acoustic sensing technology, these location
systems consist of sensors or microphones that detect
the sound of gunfire, transmitters that send a "location
message" to the dispatch center, and a computer that
receives and displays the message. When the message
arrives at the police station, the dispatcher can have a
patrol unit respond to the call.
LASD installed a trial system just days before the millennium
New Year's Eve. The department inundated citizens
with information, staging a press conference to brief
everyone from the local weekly newspapers to the major
television networks, national news agencies, and even
the foreign media. Department officials made it clear that
if a citizen fired a weapon, the system would detect it,
and deputies would not hesitate to arrest the shooter. On
December 31, 1999, in a brief 3-hour period, the Century
Station system detected 1,100 incidents of gunfire. ...

Discussed in this Brief: The findings of two field studies of acoustic
sensing systems designed to detect the sound of a muzzle blast from a
gun and, within seconds of the shot being fired, triangulate within
some margin of error the location from which the shot was fired,
before alerting the police about the gunshot. The research team
examined the effectiveness of Trilon Technology's ShotSpotter
[trademark) system, which the local police department has operated in
Redwood City, California, since early 1996, and the Alliant
Techsystems Inc.'s SECURES [trademark] system, which police instlled
for 2 months in a neighborhood with high levels of random gunfire in
Dallas, Texas, in 1996. ...
