Do have a cite for that "fact"?

To which fact are you referring? If you're referring to the silent
operation of lasers, just click your laser pointer and listen.

If you are referring to the sonic location of gun shots in urban
locations, here's a clue:

The first link is hardly a cite for your statement "These days, in the
metropolitan areas there are microphones on every traffic-controlled
intersection that can be used to triangulate the report of the weapon to
determine its location." It is a proposal written in 2001 for such a system
but quotes a DOJ report that pretty much says it would only be useful for
statistical and planning purposes. (See Below)

As for the other 524 other links via that search #2 has not a damn thing to
do with gunshot location and #3 has to do with the JFK shooting. So i
stopped looking.

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?

3.2 Reviews/Criticism of Gun Shot Detection

There are many reviews that analyze the benefits and handicaps produced by a
gun shot

detection system. In a report issued by the U.S. Department of Justice, the
pros and cons

of gun shot detection were evaluated. The following points were presented
against gun

shot detection systems.[2]


The technology is likely to increase the workloads of police officers,

particularly if departments dispatch a patrol unit to every gunfire incident

detected by a technological system.


Gunshot detection systems are not likely to lead to more arrests of people

firing weapons in urban settings because it is highly unlikely that
offenders

will stay at a gunshot location long enough for the police to arrive.

To balance the negative results obtained from the experimenting with gun
shot detection,

the department credited that the systems would be beneficial for the
following reasons.


Gunshot detection systems are likely to reveal important statistics of
rather high

citizen under-reporting rates of random gunfire problems.


Gunshot detection systems seem to offer the most potential as a

problem-solving tool and would fit nicely within the emerging problem
oriented

policing paradigm. The technology can help police identify random gunfire
hot spots and

develop strategies to address the problem.
