I'm hoping to contact a few 911 emergency operators to learn the steps
that occur when a call is received. In particular, how does an
incoming cellphone call reporting an emergency (such as a car wreck)
lead to a police officer being dispatched?

I'm including such an operator in a novel I'm researching, and want to
know what the facility looks like, who says what to whom, how the
closest officer is located, what sort of information is finally sent
to the officer, how much of the process is automatic, how much
decision-making is required, etc.

I'm somewhat familiar with the process. You might have better luck
identifying a good source through NENA (listserv@nena.org).

You have the PSAP (Public Safety Answering Point) in the USA
that houses call takers and dispatchers. At best a cell phone will
give a GPS coordinate or perhaps just a general region (southwest
of a given cell tower). Everything from that point on may have some
computer assistance, ubt it is mostly the caller talking to the call taker.

Depending on where you live, this could be an easy quest. Find out the
non-emergency phone number of you local 911 emergency center. Google should
be able to help you. Call over and explain your project. You may find that
the person who answers the phone is willing to help, either directly or by
suggesting another person in the organization who can.

Good Luck,

-Gary

It used to be that both government and the private sector were proud
of new technology upgrades. In the old days they would publish color
brochures on glossy paper to tout their accomplishment and the
benefits it would bring to the citizens or customers. Inquiries from
interested parties would be welcome and perhaps a facility tour
provided.

For whatever reasons, that is no longer the case. These days new
facilities are kept secret and hidden away under strict security.
Inquiries are looked upon with suspicion rather than welcomed.

I'm not sure what has changed to create this paranoia, but _perhaps_
it is: (1) fear of terrorism, letting terrorists know of a desirable
target and how the system works which might expose vulnerabilities
they could exploit, (2) fear of competitors, (3) fear of activist
citizen troublemakers, (4) fear of lawsuits, (5) fear of exposure of
problems in the facility they want to keep secret, (6) cost of
providing staff to respond to such inquiries.
