LETA’s Standards and Protocol
FOR THE LEGAL AND ETHICAL USE OF THERMAL IMAGING
IN SUPPORT OF LAW ENFORCEMENT
A. The mission statement of the Law Enforcement
Thermographers’ Association is to “Provide Legal and Ethical
Thermal Imaging in support of law enforcement.” (including
certified training seminars/schools on four levels; Basic,
Advanced Recertification, and Instructors; Legal Updates; a
newsletter; and numberous clinics and seminars.)
B. “LETA” maintains and endorses the scientific fact that thermal
imaging surveillance is passive and non-intrusive.
C. “LETA” maintains the position that no search warrant is
required to conduct a thermal surveillance. (however due to the
usa supreme court decision, us v. danny lee kyllo 2001, LETA
subscribes to the issuance of a search warrant for any thermal
scan involving a persons residence or where the curtilage is
evident.)
D. In addition, “LETA” endorses qualitative analysis of relative
heat differences in support of probable cause to obtain legal
search warrants. (as long as additional items or corroborating
events of probable cause exist.)
E. The same standards and protocol shall apply to thermal
imaging systems operating from airborne platforms as well as
ground based systems.
F. Each law enforcement thermographer shall be certified per
“LETA” training standards in one of the following three (3)
classifications: ----Basic,----Advanced,----Instructor.
G. “LETA” subscribes to the drug enforcement administration
thermal imaging basic training course and thus accepts the drug
enforcement administration basic certificate as criteria for “LETA”
advanced and/or instructor ratings.
H. “LETA” has written, approved, and certified training courses
at the basic, advanced recertification, and instructor levels. The
purpose of all four (4) levels of training is to standardize law
enforcement thermography in accordance with current federal,
state, and local laws.
I. Additionally, it is “LETA’s” intent to comply with all approved
law enforcement policies and procedures.
J. “LETA” recognizes twelve (12) current law enforcement
applications for the use of thermography. these applications are
not finite, nor limited in number as law enforcement has, and will
continue to develop new applications as the law and science
evolve.
K. As of the publication of these standards and protocol, the
twelve (12) law enforcement applications are as follows:
General surveillance:
1. Search and rescue
2. Fugitive searches
3. Vehicle pursuits
4. Flight safety
5. Marine and ground surveillance
6. Perimeter surveillance
7. Officer safety
Specialized surveillance:
8. Structure profiles
9. Disturbed surface scenario
10. Environmental law enforcement
11. Vehicle compartments/profiles
12. Accident investigations/skidmarks
L. No broad area searches will be conducted in support of
specialized surveillance applications. Specialized surveillance
will be conducted only when supported by specific, corroborating
items or events of probable cause.
M. Until specific thermal imaging science evolves, “LETA” does
not endorse the use of thermal imaging to state that clandestine
drug laboratories exist. (However, thermal surveillance may be
used to locate chemical spills or dump sites which may indicate a
drug lab. Not structure profiles as in the application for indoor
cannabis grow sites.)
N. “LETA” by formation does not endorse any specific company
or corporation involved in the manufacture of thermal imagers.
However, “LETA” does allow corporate and individual
memberships of persons from the thermal imaging industry.
Those individuals are encouraged to participate in LETA/DEA
schools and to bring scientific developments to the attention of
“LETA” to expand both applications and protocol.
0. “LETA” endorses and adopts current National Guard bureau
policy regarding the use of thermal imagery by state National
Guard personnel in support of law enforcement.
(LETA reserves the right to amend these standards and
protocols as required by science or changes in the law.

Thermographers’ Association Board of Directors.)
