Preventing Torture An Operational Guide for National Human Rights Institutions - Updated Edition
The absolute prohibition of torture is sometimes questioned by people on the grounds of security
or counter-terrorism using a hypothetical “ticking bomb” scenario. This scenario involves the police
capturing a terrorist whom they suspect has placed a bomb that is about to explode in the middle of
a large city. The police believe that only torture will make the suspect disclose the information needed
to prevent the deaths of thousands of people. The question is posed: “May the person be tortured?”
This hypothetical situation operates by manipulating the emotional reactions of the audience and
assumes that:
• there is a known threat
• the attack is imminent
• the attack will kill a large number of people
• the person in custody is the perpetrator of the attack
• the person has information that will prevent the attack
• only torturing the person will provide the information in time to prevent the attack.
In real life situations, however, one or more of these assumptions are always invalid.
The assumptions that underpin the “ticking bomb” argument can also, by extension, be used to try
and justify torture in a wider range of situations. For instance, we might ask ourselves if our reaction to
the “ticking bomb” scenario would be different if we were not sure whether the suspect was actually
connected with the bomb plot, or whether they were in fact connected to terrorism at all; whether the
suspect had any reliable information about the threat; if the threat was several days or a week away;
or whether the threat was even real.
The scenario also contains some hidden assumptions that should be defused.
• The motive of the torturer is to get the necessary information, with the genuine intention
of saving lives. However, even if the torturer did begin with the genuine motive of obtaining
information, torture corrupts the perpetrator. This is an inherent part of the act of torture. Further,
the assumption that the objective is purely to gather information is too simplistic. In real life
situations other motivations and emotions, such as anger, punishment, and the exercise of
power, can take over.
• It is an isolated situation, not to be repeated regularly.
However, it is part of the nature of torture that any authorization of such acts invariably leads to a
slippery slope, where the use of torture becomes more widespread within the institution.27
Last but not least, the scenario assumes that the suspect will provide valuable information under
torture. However, there is now large and growing scientific research showing that torture is ineffective
in gathering accurate and reliable information and that rapport-based, non-coercive methods for
interviewing are more effective for gathering information.
Following the 2016 call by the Special Rapporteur on torture in his last report to the General Assembly,28
Principles on Effective Interviewing for Investigations and Information gathering have been drafted,29
a process supported by several UN bodies.30
