It's one thing to be betrayed by an enemy, it's another thing to be betrayed by a friend. His shame will last forever.
Espionage by the Numbers:
A Statistical Data Base
By Lynn F. Fischer
DSS/Security Research Center
The Security Research Center maintains an unclassified espionage case database in order to gain a better understanding of the crime of espionage. Much is known about individual espionage cases from detailed investigative reports after the arrest. But it is difficult to make sound generalizations about this type of behavior without data on a wide range of variables for many cases.
The SRC database includes information on all Americans arrested and convicted of espionage against the U.S. since World War II. It contains information on over 100 variables for 148 cases from 1945 to through 1998. It is based only on media reports, trial records, and other unclassified documents so information on quite a few cases is incomplete. 1
Why Pollard? What about the others? Many of them were US citizens. Nobody was punished as severely as Pollard.
