John Nagle read the E911 Document. He drew his own conclusions. And
he presented Zenner and his defense team with an overflowing box of
similar material, drawn mostly from Stanford University's engineering
libraries. During the trial, the defense team--Zenner, half-a-dozen
other attorneys, Nagle, Neidorf, and computer-security expert Dorothy
Denning, all pored over the E911 Document line-by-line.

On the afternoon of July 25, 1990, Zenner began to cross-examine a
woman named Billie Williams, a service manager for Southern Bell in
Atlanta. Ms. Williams had been responsible for the E911 Document.
(She was not its author--its original "author" was a Southern Bell
staff manager named Richard Helms. However, Mr. Helms should not bear
the entire blame; many telco staff people and maintenance personnel had
amended the Document. It had not been so much "written" by a single
author, as built by committee out of concrete-blocks of jargon.)

Ms. Williams had been called as a witness for the prosecution, and had
gamely tried to explain the basic technical structure of the E911
system, aided by charts.

Now it was Zenner's turn. He first established that the "proprietary
stamp" that BellSouth had used on the E911 Document was stamped on
EVERY SINGLE DOCUMENT that BellSouth wrote--THOUSANDS of documents.
"We do not publish anything other than for our own company," Ms.
Williams explained. "Any company document of this nature is considered
proprietary." Nobody was in charge of singling out special
high-security publications for special high-security protection. They
were ALL special, no matter how trivial, no matter what their subject
matter--the stamp was put on as soon as any document was written, and
the stamp was never removed.

Zenner now asked whether the charts she had been using to explain the
mechanics of E911 system were "proprietary," too. Were they PUBLIC
INFORMATION, these charts, all about PSAPs, ALIs, nodes, local end
switches? Could he take the charts out in the street and show them to
anybody, "without violating some proprietary notion that BellSouth has?"

Ms Williams showed some confusion, but finally agreed that the charts
were, in fact, public.

"But isn't this what you said was basically what appeared in Phrack?"

Ms. Williams denied this.

Zenner now pointed out that the E911 Document as published in Phrack
was only half the size of the original E911 Docume
