FBI Surveillance Activity Data
On January 14, 1997, the FBI issued a notice setting forth projected
increases in law enforcement wiretapping and other electronic
surveillance activity in coming years. Under legislation adopted
in 1994, the federal government can require telephone companies
to install additional equipment ("capacity"), at government
expense, to accommodate these projected increases in electronic
surveillance activity.
The narrative portion of the notice was printed in the Federal
Register. However, the very detailed appendices, which embody
the government's proposed requirements, were made available only
in hard copy to reporters in New York and at the FBI "reading
room" in Washington, DC.
Wireline Data
CDT has obtained the files in electronic form and we have loaded
the entire 81 page appendix for wireline services. The appendix
has three components:
- A baseline showing the one-day peak in electronic surveillance
activity for each county in the nation during the period 1/1/93
to 3/1/95 -- that is, for each county, the total number of intercepts
that were conducted simultaneously by federal, state and local
authorities on the busiest surveillance day in the study period.
On the accompanying charts, this one day peak is the third column
of numbers.
- A projection, based on past growth, of anticipated one-day
peaks of surveillance activity for each county in 1998. On the
accompanying charts, this is the first column of numbers.
- A projection, based on past growth, of anticipated one-day
peaks of surveillance activity for each county in the year 2004.
On the accompanying charts, this is the middle column of numbers.
We have established a separate file for each state.
Cellular Data
The data for cellular services covers 306 Metropolitan Statistical Areas (MSAs). [We did not include the 428 Rural Statistical Areas (RSAs).] As with the wireline data, the cellular appendix has three components:
- A baseline showing the one-day peak in electronic surveillance
activity for each MSA in the nation during the period 1/1/93
to 3/1/95 -- that is, for each MSA, the total number of intercepts
that were conducted simultaneously by federal, state and local
authorities on the busiest surveillance day in the study period.
On the accompanying charts, this one day peak is the third column
of numbers.
- A projection, based on past growth, of anticipated one-day
peaks of surveillance activity for each MSA in 1998. On the
accompanying charts, this is the first column of numbers.
- A projection, based on past growth, of anticipated one-day
peaks of surveillance activity for each MSA in the year 2004.
On the accompanying charts, this is the middle column of numbers.
Appendix B: Cellular Services Data
PCS Data
The PCS data covers 51 Metropolitan Trading Areas (MTAs) and 493 Basic Trading Areas (BTAs). The appendix also has three components:
- A baseline showing the one-day peak in electronic surveillance
activity for each MTA/BTA in the nation during the period 1/1/93
to 3/1/95 -- that is, for each MTA/BTA, the total number of intercepts
that were conducted simultaneously by federal, state and local
authorities on the busiest surveillance day in the study period.
On the accompanying charts, this one day peak is the third column
of numbers.
- A projection, based on past growth, of anticipated one-day
peaks of surveillance activity for each MTA/BTA in 1998. On the
accompanying charts, this is the first column of numbers.
- A projection, based on past growth, of anticipated one-day
peaks of surveillance activity for each MTA/BTA in the year 2004.
On the accompanying charts, this is the middle column of numbers.
