Background paper on pk's Combined Use of Interrogation Teanicrues 
Note: This paper provides further background information and details on High-value Detainee (HVD) interrogation techniques to support documents CIA has previously provided .the Department of 
Justice. 
This paper focuses strictly on the topic of combined use of 
interrogation techniques. 
The purpose of interrogation is to persuade High-Value Detainees (HVD) to provide threat information and terrorist intelligence in a timely manner„ to allow the US Government to identify and
disrupt terrorist plots 
.1nd to collect critical intelligence on al-Oa'ida 

In support 
of information previously sent to the Department of Justice, this paper provides additional background on how interrogation techniques are used, in combination and separately, to achieve 
interrogation objectives. Effective interrogation is' based on 
) the concept of using both physical and psychological pressures in a comprehensive, systematic, and cumulative manner to influence HVD behavior, to overcome a detainee's resistance posture. The goal of interrogation is to create a state of learned helplessness and dependence conducive to the collection 
of intelligence in a predictable, reliable, and sustainable' 
Manner. For the purpose of this paper, the interrogation 
process can be broken into three separate phases: Initial 

Conditions; Transition to Interrogation; and Interrogation. 
A. Initial Conditions. Capture, contribute to the physical and psychological condition 
of the HVD prior to the start of interrogation. Of these,
"capture shock" and detainee reactions 

are factors that may vary significantly between detainees '

Regardless of their previous environment and . 
experiences, once an HVD is turned over to CIA a predictable set 
of events occur: 

1) Rendition, 

a. The HVD is flown to a Black Site 

A medical examination is conducted prior to 
the flight. During the flight, the detainee is 
securely shackled and is deprived of sight and sound 
through the use of blindfolds, earmuffs, and hoods. 

. There is

• 
no interaction with the HVD during this rendition 
movement except for periodic, discreet assessments by 

the on-board medical officer, 

b, upon arrival at the destination airfield, the 
HVD is moved to the Black Site under the same 
conditions and using appropriate security procedures. 

2) Reception at Black Site, The HVD is subjected to 
administrative procedures and medical assessment upon 
arrival at the Black Site. 

the HVD finds himself in the complete 
control of Americans; 

the procedures he is subjected o are 
precise, quiet, and almost clinical; and no one is 
mistreating him. While each HVD is different, the 
rendition and reception process generally Creates 
significant apprehension in the HVD because of the enormity 

_

_ _ _ _and_suddenness of.the _chang.e_ in environment, _ the . _ 
uncertainty about what will happen next, and the potential 
dread an HVD, might have of US custody, Reception 
procedures include: 

_ 

a. The HVD's head and face are shaved.

TO12_SegeRIST-1 MageRITTORFW/MR3. 
. b. A series of photographs are taken of the HVD while nude to document the physical condition of the HVD upon arrival. 
c. 
A Medical Officer interviews the HVD and a medical evaluation is conducted to assess the physical condition of the HVD, The medical officer also determines if there are any contraindications to the use of interrogation techniques. 

d. 
A Psychologist interviews the HVD to assesshis mental state. The psychologist also determines if there are any contraindications to the use of interrogation techniques. 


Transitioning to Interrogation - The Initial Interview. Interrogators use the Initial Interview to assess the initial resistance posture of the HVD and to determine--in a relativelybenign environment--if the HVD intends to willingly participate with CIA interrogators. The standard on participation is set very high during the Initial Interview. The HVD would have to willingly provide information on actionable threats and location information on High-Value Targets at large--not lower level information--for interrogators to continue with the neutralapproach. -

C. Tnterrogation. 
For 
descriptive purposes,'these techniques can be separated into 
three categories: Conditioning Techniques; Corrective 

Techniques; and Coercive Techniques. To more completely ,describe the three Categories of techniques and their effects, we begin with a summary of the detention conditions that are used in all CIA HVD facilities and that may be a factor in interrogations. 
1) Existing detention conditions. Detention conditions are not interrogation techniques, but they have an impact on the detainee undergoing interrogation. Specifically, the HVD will be exposed to white noise/loud sounds (not to exceed 79 decibels) and constant light during portions of the interrogation process, These conditions provide additional operational security: white noise/loud sounds mask conversations of staff members and deny the HVD any auditory.clues about his surroundings and deter and disrupt the HVD's potential efforts to communicate with other detainees, Constant light provides an improved environment for Black Site security, medical, psychological, and interrogator staff to monitor the HVD. 
2) Conditioning Techniques. The HVD is typically reduced-to a baseline, dependent state using the three 
-----interrogation techniques-discussed below in combination.--Establishing this baseline state is important to demonstrate to the HVD that he has no control over basic human needs. The baseline state also creates in the detainee a mindset in which he learns to perceive and value his personal welfare, comfort, and immediate needs more than the information he is protecting. The use of these

TQ 3T/. 

conditioning techniques do not generally bring immediate 
results; rather, it is the cumulative effect of these 

techniques, used over time and in combination with other 

interrogation techniques and intelligence exploitation 

methods, which achieve interrogation objectives. These 

conditioning techniques require little to no physical 

interaction between the detainee and the interrogator. The 

specific conditioning interrogation techniques are 

a. 
Nuglty. The HVD's clothes are taken and he 
remains nude until the interrogators provide clothes 
to him. 


b. 
Sleep Deprivation. The HVD is placed in the 
vertical shackling position to begin sleep 
deprivation. Other shackling procedures may ,be used 
during interrogations. The detainee is diapered for 
sanitary purposes; although the diaper is not used at 
all times. 


c. 
Dietary manipulation. The HVD is fed Ensure 
Plus or other food at regular intervals. The IND 
receives a target of 1500 calories per day per OMS 
guidelines. 



3) Corrective Techniques. Techniques that require 

physical interaction between the interrogator and detainee 
are used principally to correct, startle, or to achieve 
another enabling objective with the detainee. These 
techniques-the insult slap, abdominal slap, facial hold, 
and attention grasp-are not used simultaneously but are 
often used interchangeably during an individual 
interrogation session. These techniques generally are used 

while the detainee is subjected to the conditioning 
techniques outlined above (nudity, sleep deprivation, and 
dietary manipulation). Examples of application include; 

The insult slap often s the 
first physical technique used with an HVD once an 
_

inter:,o 

be nude, in sleep deprivation, and subject to dietary 

manipulation, even though the detainee will likely 

feel little effect from these techniques early in the 

interrogation. The insult slap is used sparingly but 
periodically throughout the interrogation process when 
the interrogator needs to immediately correct the

o.mJ./iNCTPENARCOgnial 
detainee or provide a consequence to a detainee's 
response or non-responee. The interrogator will 
continually assess the effectiveness of the insult 
slap and continue to employ it so long as it has the 
desired effect on the detainee. Because of the 
physical dynamics of the various techniques, the 
insult slap can be used in combination with water 
dousing or kneeling stress positions. Other 
combinations are possible but may not be practical, 
b. Abdominal Slap. The abdominal slap is similar to the insult slap in application and desired result. It provides the variation necessary to keep a high level of unpredictability in the interrogation process. The abdominal slap will be used sparingly and periodically throughout the interrogation process when the interrogator wants to immediately correct the detainee 
, and the interrogator will continually assess its effectiveness. Because of the physical dynamics of the various techniques, the abdominal slap can be used in combination with water dousing, stress positions, and wall standing, Other combinations are possible but may not be practical, 
c, Facial Hold. The facial hold is a corrective technique and is used sparingly throughout interrogation. The facial hold is not painful and is used to correct the detainee in a way that 
demonstrates the interroaator's control over the HVD, 
Because of the physical, dynamics of the various techniques, the facial hold can be used in combination with water dousing, stress positions, and wall standing. Other combinations are possible but may not be practical. 
d, Attention Grasp . . 
It may be used several times in the same interrogation. This technique is usually applied 
grasp the HVD and pull him

TOD–ntigTi IMOROldrifiiC67/4E6:-

into. close proximity of the interrogator (face to 
face). Because of the phySical dynamics of the • 
various techniques, the attention grasp can be used in 
combination with water dousing or kneeling stress 
positions. Other combinations are possible but may 
not be practical. 

4) Coercive Techniques. Certain interrogation 
techniques place the detainee in more physical and 
psychological stress and, therefore, are considered more 
effective tools in persuading a resistant HVD to 
participate with CIP interrogators.. These techniques— 
walling, water dousing, stress positions, wall standing, 
and cramped confinement—are typically not used in 
combination, although some combined use is possible. For 
example, an HVD in stress.positions or wall standing can be 
water doused at the same time. Other combinations of these 
techniques may be used while the detainee is being 
subjected to the conditioning techniques discussed above 
(nudity, sleep deprivation, and dietary manipulation). 
Examples of coercive techniques include: 

a. Walling. Wailing is one of the most 
effective interrogation techniques because it wears 
down the HVD physically, heightens uncertainty in the 
detainee abott what the interrogator may do to him, 
and creates a sense of dread when the HVD knows he is 
about to be walled again. 

aterrogator 

At HVD may 
be walled one time (one impact with the wall) to make . 
a point or twenty to thirty times consecutively when 
the interrogator requires a more significant response 
to a question, During an interrogation session that 
is designed to be intense, an HVD will be walled 
multiple times in the session. Because of the 

_ physical dynamicS .of walling, it is impractical to use 
it simultaneously with other corrective or coercive 
techniques, 

b. Water Dousing. The frequency and duration of 
water dousing Applications are based on water 
temperature and other safety considerations as

i its 4": 1
Tql.P.-68614:Ti 0 

established by OMS guidelines. It is an effective 
interrogation technique and may be used frequently 

within those guidelines. The physical dynamics of water dousing are such that it can be used in combination with other corrective and coercive techniques. ?s noted above, an HVD in stress positions or wall standing can be water doused. Likewise, it is possible to use the insult slap or abdominal slap with an EVD during water dousing. 
o.• Stress Positions. The frequency and duration 
of use ofthe stress positions are based on the interrogator's assessment of their continued effectiveness during interrogation. These techniques 
are usually self-limiting in that temporary muscle 
fatigue usually leads to the HVD being unable to 
maintain the stress position after- a period of time. 
Stress positions requiring the HVD to be in contact 

with the wall can be used in combination with water dousing and abdominal slap. Stress positions requiring the HVD to kneel can be used in combination with water dousing, insult slap, abdominal slap, facial hold, and attention grasp. 
d. Wall Standing. The frequency and duration of 
wall standing are based on the interrogator's assessment of its continued effectiveness during interrogation. Wall standing is usually self-limiting in that temporary muscle fatigue usually leads to the HVD being unable to maintain the position after a 
period of time. Because of the physical dynamics of the various techniques, wall standing can be used in combination with water dousing and abdominal slap. While other combinations are possible, they may not be practical. 
e. Cramped Confinement, Current 0M3 guidance on 
the duration of cramped confinement limits confinement in the large box to no more than 8 hours at a time for no. morp_than 1B hours a day, and confinement in the small box to 2 hours. 
Because of the unique aspects of cramped confinement, it cannot be used in

D. Interrogation This section provides a -look at a prototybical interrogation with an 'emphasis on the application. of interrogation techniques, in combination and separately. 
Session One., 

a. The HVD is brought into the interrogation 
room, and under the direction of the interrogators, 
stripped of his clothes, and placed into shackles

b. 
The HVD is placed standing with his back to 
the walling wall. The HVD remains hooded. 


c. 
Interrogators approach the HVD, place the 
wailing collar over his head-and around his neck, and . 
stand in front of the HVD. 



d. The interrogators remove the HVD's hood and 

explain the HVD's situation to him, tell 
him that the interrogators will do what it takes to 
get important information, and that he can improve his 
conditions immediately by participating with the 
interrogators. The insult slap is normally used as 
soon as the HVD does or says anything inconsistent 
with the interrogators' instructions. 

e. 

If appropriate, an 
insult slap or abdominal slap will follows 

f. 
The interrogators will likely use walling 
once it becomes clear that the HVD is lying, 
withholding information, or using other resistance 
techniques. 


g. 
The sequence may continue for several more iterations as the interrogators continue to measure the HVD's resistance posture and apply a negative consequence to the HVD's 


.resistance efforts. 

h. The interrogators, assisted by security 
officers (for security purposes) will place the HVD in

room. The first interrogation session terminates at 
this point. 

j. This first interrogation session may last 
from 30 minutes to several hours based on the 
interrogators' assessment of the HVD's resistance 
posture. 

The three Conditioning Techniques were used to 
bring the itn to a baseline, dependent state 
conductive to meeting interrogation objectives in a 
timely manner. 

3) Session Two. 

a. The time period between Session One and 

Session Two could be as brief as one hour or more than 
24 hours

In addition, the 
medical and psychological personnel observing the 
interrogations must advise there are no 

contraindications to another interrogation session.

C. Like the first session, interrogators 
approach the HVD, place the walling collar over his 
head and around his neck, and stand in front of the

The interrog'itors 
will likely use walling once interrogators determine 
the HVD is intent on maintaining his resistance 

posture, 

f. The sequence 
may continue for multiple iterations as the 
interrogators continue to measure the HVD's resistance 

posture. 

• g. To increase the pressure on the HVD, 

water douse the HVD for several minutes. 

h. 
The interrogators, assisted by security 
officers, will place the HVD back into the vextical.

Dietary manipulation also continues, and the HVD 
remains nude, White noise (not to exceed 79db) is 
used in the interrogation room. The interrogation 
session terminates at this point, 


i. 
As noted above, the duration of this session may last from 30 minutes to several hours based on the interrogators' assessment of the HVD's resistance posture. In this example of the second session, -the following techniques were used: sleep deprivation, nudity, dietary manipulation, walling, water dousing, attention grasp, insult slap, and abdominal slap.

a. 

In addition, the medical and 

psychological personnel observing the interrogations must find no contraindications to continued interrogation. 
b. 
The HVD remains in sleep deprivation, dietary manipulation and is nude. 

P. 
Like the earlie'r sessions, the HVD begins the session standing against the walling wall with the walling collar around his neck. 


d, If the HVD is still maintaining a resistance posture, , interrogators will continue to use walling and water dousing. All of the Corrective TechniqUes, 
(insult s1aD, abdominal slap, facial hold, attention 
rasp)may be used several times during this session based on the responses and actions of the HVD. Stress positions and wall standing will be integrated into interrogations 
Intense questioning and walling would be repeated 
multiple times. 
Interrogators will often use one technique to support another. As an example, interrogators would tell an HVD in a stress position that he (HVD) is going back to the walling wall (for walling) if he fails to hold the stress position until told otherwise by the HVD. This places additional stress on the HVD who typically

interrogators will remind the HVD that he is responsible for this treatment and can stop it at any time by cooperating with the interrogators. 
e. The interrogators, assisted by security officers, will place the HVD back itto the vertical shackling pobition to resume sleep deprivation. Dietary manipulation alSo continues, and the HVD remains nude. White noise (not to exceed 79db) is used in the interrogation room. The interrogation session terminates at this point. In this example of the . third session, the following techniques were used: sleep deprivation, nudity, dietary manipulation, walling, water dousing, attention grasp, insult slap, abdominal slap, stress positions, and wall standing. 
5) Continuing Sessions. 
Interrogation techniques assessed as being the most effective will be emphasized while techniques will little assessed effectiveness will be minimized,

Interrogation techniques may still be applied as 
required, but become less frequent,

OD average, the actual .use of 
interrogation technique! 
can vary upwards to fifteen days based 
on the resilience of the !iVD. 

If the interrogation 
team anticipates the potential need to use 
interrogation techniques beyond the 30-day approval_ 
period, it will submit a new interrogation plan to HQS 
for evaluation and approval. 

2. Summary. 

. 	since the start of this program, interrogation techniques have been used in combination and separately to achieve critical intelligence collection objectives. 
0 The use of interrogation techniques in combination is 
essential to the creation of an interrogation_ environment 
conducive to intelligence collection. HVDs are well­trained, often battle-hardened terrorist operatives, and 
highly committed to jihad. They are intelligent and 
resourceful leaders and able to resist standard 
interrogation approaches. 

However, there is no template or script that states with 
certainty when and how these techniques will be used in 
combination during interrogation. However, the exemplar 
aboVe is a fair representation of how these techniques 

are actually employed. 

17 

ild:15.3RM 

All CIA interrogations are conducted on the basis of the 
"least coercive measure" principle, Interrogators employ 

interrogation techniques _in an escalating manner 
consistent with the HVD's responses and actions. 

Intelligence production is more sustainable over the long 
term if the actual use of interrogation techniques 
diminishes steadily and the interrogation environment 
improves in accordance with the {VD's demonstrated 
consistent participation with the interrogators,
