This policy brief aims to re-examine the situation of ISIS captives in detention Iraq and Syria, serious security threat that it might pose on long term, especially, after loosening COVID-19 restrictions movement. proposes extract lessons from Algerian experience during 1990s counterterrorism. The approach counterterrorism relies both military soft method. Global War Terror against was successf...

In America, Britain and Australia the threat of terrorism has been used to justify radical new legislation that gives police and intelligence agencies unprecedented powers to detain and question people believed to have information connected to terrorism. In this paper I explore the nature of the threat of non-state terrorism—threat to national security and the well-being of citizens. I argue th...

Camera surveillance has recently gained prominence in policy proposals on combating terrorism. We evaluate this instrument of counterterrorism as resting on the premise of a deterrence effect. Based on comparative arguments and previous evidence on crime, we expect camera surveillance to have a relatively smaller deterrent effect on terrorism than on other forms of crime. In particular, we emph...

Introduction Over the past decade, decapitation, particularly high-value targeting (HVT), has come into vogue and is being increasingly applied in a variety of counterterrorism, counterinsurgency, and anti-organized crime settings around the world. There are several reasons for this widespread adoption of high-value targeting as a dominant interdiction pattern. First, there is a long tradition ...

Two areas that are increasingly studied in the game-theoretic literature on terrorism and counterterrorism are collective action and asymmetric information. One contribution of this chapter is a survey and extension of continuous policy models with differentiable payoff functions. In this way, policies can be characterized as strategic substitutes (e. g., proactive measures), or strategic compl...

Data mining is becoming a useful tool for detecting and preventing terrorism. This paper first discusses some technical challenges for data mining as applied for counterterrorism applications. Next it provides an overview of the various types of terrorist threats and describes how data mining techniques could provide solutions to counterterrorism. Finally some privacy concerns and potential sol...

The success of Stackelberg Security Games (SSGs) in counterterrorism domains has inspired researchers’ interest in applying game-theoretic models to other security domains with frequent interactions between defenders and attackers, e.g., wildlife protection. Previous research optimizes defenders’ strategies by modeling this problem as a repeated Stackelberg game, capturing the special property ...

The present study aimed to (a) demonstrate the effect of positive-negative framing on experienced criminal justice decision makers, (b) examine the debiasing effect of visually structured risk messages, and (c) investigate whether risk perceptions mediate the debiasing effect of visual aids on decision making. In two phases, 60 senior police officers estimated the accuracy of a counterterrorism...
