This is part of a 23-part, 2,900 page, file, "Surreptitious Entries," published on the FBI Freedom of Information Web site on December 17, 1999: http://foia.fbi.gov/entries.htm. The material was declassified in 1982-83. Some of it was publicized in the 1975 US Senate (Church Committee) hearings on intelligence activities.

Parts of related interest describe the FBI's history of the use of electronic surveillance:

"Microphones Policy Brief," July 12, 1966: http://foia.fbi.gov/entries/entries9b.pdf (115 pages; 4.2MB)

"Electronic Surveillances [wiretaps and microphones policy]," June 23, 1969: http://foia.fbi.gov/entries/entries12.pdf (16 pages; 914KB)

"JUNE" is an FBI code word for "highly confidential and anonymous sources," wiretaps, and other forms of surveillance, some of which involved surreptitious entries.

	INTERNAL SECURITY - C.

	In connection with the development of highly confidential
and anonymous sources, there has been utilized successfully by the
New York Office a new and practical investigative technique, which
may prove of value to other offices in the development of those
sources in their territory. (C)(U)

	The technique involves the use of "Booties", which is a
type of shoe cover commonly used by window dressers in their trade.
These "Booties" are used by window dressers in order to allow them
to walk around a display window without leaving shoe or dirt marks
on the floors, rugs or other material used in the display. The
"Booties" are slipped on over their shoes and obviates the necessity
of removing their shoes. (C)(U)

	It should be noted that the "Booties" are comparatively
small in bulk and can easily be folded to handkerchief size and
carried in the pocket of the user. The very practical and advantageous
use of the "Booties" in connection with the development of highly
confidential and anonymous sources is realized on snowy and rainy
days when shoes become wet or muddy. On such days, these "Booties"
can be easily and quickly slipped over the wet shoes just prior to
entering the particular apartment, office, etc. and will allow move-
ment within the premises without leaving "telltale" stains or smears.
Upon exit they can be removed just as easily and place in the user's
pocket thus affording a higher degree of security and a greater
degree of movement while in the premises. (C)(U)

JUNE Letter to Director

	It was ascertained too, during this operation, that the
use of the "Booties" also cut down considerably the amount of
usual and ordinary floor noises made by walking on floor boards,
linoleum, etc. and permitted a much quieter movement within the
premises. This indicates a definite additional advantageous use
of the "Booties" even on dry days where silent movement is of the
essence in maintaining a high degree of security. (C)(U)

	The New York Office has purchased a half dozen of these
"Booties", which are currently being used by the agents engaged
in this activity, and one pair is being forwarded to the Bureau with
this letter for examination and by way of explanation. (C)(U)

	The "Booties" were purchased in New York from a shoe supply
wholesale house at the cost of 25¢ per pair. They also can be
purchased through any retail shoe store at probably a slightly
higher cost and should be accessible through these outlets to any
of the Bureau offices (C)(U)
