This article examines Israel's attempts to weaken and defeat the Lebanese Hizballah. It reviews Hizballah's rise after the 1982 Israeli invasion of Lebanon, Hizballah's successful effort to force Israeli forces to withdraw from Lebanon in 2000, the 2006 war, and Israeli attempts to deter Hizballah. The article argues that Israel has largely failed to defeat Hizballah militarily and politically. Israel's experience offers lessons for how terrorist groups learn, the effectiveness of terrorist attrition strategies against casualty-sensitivity states, the difficulties in coercing terrorist groups, and the importance of an information strategy. Finally, Israel's clash with Hizballah indicates the importance of thinking of groups that are large and multi-faceted from a counterinsurgency paradigm.  相似文献

The article examines Israel's successes and failures during the Second Intifada. It argues that Israel's advances came from an effective counterterrorism campaign involving a mix of military operations, defensive measures, and in particular improved intelligence gathering. Domestic resilience also proved strong in the face of a brutal terrorism campaign. Yet long-term victory remains elusive for Israel. Deterrence, always difficult against terrorist groups, is growing harder for Israel. Hamas's control of Gaza, and the mistrust and hatred sown during the Second Intifada, have hindered a political deal between Israel and moderate Palestinians. Much of what went into successful counterterrorism, notably the security barrier and the aggressive campaign of raids and arrests, does not jibe with most visions of what peace would look like and makes a deal harder to achieve. To make a peace deal work, Israeli counterterrorism must change, with measures including relocating parts of the security barrier, bolstering moderate Palestinian politicians, and working with, as opposed to undermining, Palestinian security forces in the West Bank.  相似文献

This article examines whether the outbreak of an insurgency after the U.S. invasion of Iraq was an avoidable policy failure or whether the structural conditions surrounding the occupation made such an outbreak inevitable. Several U.S. policy mistakes, in particular the deployment of too few troops, a lack of comprehensive political and military planning for the occupation, disbanding the Iraqi military, the failure to establish a government in waiting, and overly aggressive de-Baathification, greatly exacerbated rather than ameliorated the various structural problems. More fundamentally, structure and policy choices interacted at all levels to explain the Iraq failure. The unavoidable conditions that coalition forces encountered in Iraq—a divided society devastated by years of war, sanctions, and misrule—and the political context in the United States made the challenge for successful policy execution difficult. This structure constrained and delimited the options open to U.S. policy makers but, even within those narrow limits, the United States made many bad choices that further diminished the chances of success.

A particularly important series of policy mistakes occurred well in advance of the buildup to war itself. The orientation of the U.S. armed forces away from counterinsurgency, the failure to establish a political settlement before invasion, and other controllable policy choices in the prewar period all led to enormous difficulties during the occupation itself. Thus, by the time of the invasion, these policy choices had become almost like structural constraints and the failures had a snowballing effect, making policy corrections far more difficult.  相似文献

This paper provides a review of recent investigations on the image processing techniques used to match spent bullets and cartridge cases. It is also, to a lesser extent, a review of the statistical methods that are used to judge the uniqueness of fired bullets and spent cartridge cases. We review 2D and 3D imaging techniques as well as many of the algorithms used to match these images. We also provide a discussion of the strengths and weaknesses of these methods for both image matching and statistical uniqueness. The goal of this paper is to be a reference for investigators and scientists working in this field.  相似文献

Abstract

Post Conviction Clinical Polygraph Examination Testing (Lie Detector Testing) offers significant opportunities for assessing, treating and monitoring sex offenders. This article briefly reviews the historical development of polygraph techniques including the physiological measures employed, the administration of the polygraph and the interpretation of data collected. Criticisms of polygraphy are explored and information concerning the scientific acceptability of these procedures is given. The current influence of polygraphy in sex offender work is reviewed. Evidence is given of the utility of polygraphy in reducing denial, improving treatment outcomes and more effectively supervising sex offenders on probation or license. Cost benefit considerations are examined, as well as the need for further controlled research and future regulation of the polygraph, if it is to be introduced in Britain. Planned UK Trials are described.  相似文献

Objectives

To test the effects of short-term police patrol operations using license plate readers (LPRs) on crime and disorder at crime hot spots in Mesa, Arizona.

Methods

The study employed a randomized experimental design. For 15 successive 2-week periods, a four-officer squad conducted short daily operations to detect stolen and other vehicles of interest at randomly selected hot spot road segments at varying times of day. Based on random assignment, the unit operated with LPRs on some routes and conducted extensive manual checks of license plates on others. Using random effects panel models, we examined the impact of these operations on violent, property, drug, disorder, and auto theft offenses as measured by calls for service.

Results

Compared to control conditions with standard patrol strategies, the LPR locations had reductions in calls for drug offenses that lasted for at least several weeks beyond the intervention, while the non-LPR, manual check locations exhibited briefer reductions in calls regarding person offenses and auto theft. There were also indications of crime displacement associated with some offenses, particularly drug offenses.

Conclusions

The findings suggest that use of LPRs can reduce certain types of offenses at hot spots and that rotation of short-term LPR operations across hot spots may be an effective way for police agencies to employ small numbers of LPR devices. More generally, the results also provide some support for Sherman’s (1990) crackdown theory, which suggests that police can improve their effectiveness in preventing crime through frequent rotation of short-term crackdowns across targets, as it applies to hot spot policing.  相似文献

There is a debate in the literature on referendum voting as to whether these occasions are opportunities for voters to express issue preferences in the absence of partisan politics or whether they simply serve as referendums on the current government. In part, this latter, second order account is assumed to be driven by the amount and content of media coverage, and hence information about the referendum, that is available to voters. In this paper, we address the second order question and demonstrate that holding elections concurrently both reduces the amount of media attention to the second order contest—the AV referendum in Scotland, Wales and Northern Ireland where national elections were held—and moderates media priming, thereby affecting the salient cues in the decision making of voters in those contexts.  相似文献
