Once again: risk of injury caused by blank pistols

The nature and extent of the use of blank pistols in Hamburg (according to the Hamburg crime statistics about 300 to 400 such cases per year; 34 cases involving head and neck wounds from 1989 to 1999 were investigated at our institute; among these 8 suicides, no homicide) as well as patterns of injuries caused by close distance blank pistol shots were analysed. 7 of these cases are described in detail. The results of our studies corroborate the warning statements made by many criminological and medico-legal experts regarding the danger inherent in these allegedly harmless weapons. Blank cartridge pistols can, when shot from a close distance, cause most severe injuries involving penetration into body cavities and bodily organs (especially in the head and neck), and even perforation of the skull. Therefore, we call for a much stricter control of weapons of this kind.     

Open-source intelligence and privacy by design

As demonstrated by other papers on this issue, open-source intelligence (OSINT) by state authorities poses challenges for privacy protection and intellectual-property enforcement. A possible strategy to address these challenges is to adapt the design of OSINT tools to embed normative requirements, in particular legal requirements. The experience of the VIRTUOSO platform will be used to illustrate this strategy. Ideally, the technical development process of OSINT tools is combined with legal and ethical safeguards in such a way that the resulting products have a legally compliant design, are acceptable within society (social embedding), and at the same time meet in a sufficiently flexible way the varying requirements of different end-user groups. This paper uses the analytic framework of privacy design strategies (minimise, separate, aggregate, hide, inform, control, enforce, and demonstrate), arguing that two approaches for embedding legal compliance seem promising to explore in particular. One approach is the concept of revocable privacy with spread responsibility. The other approach uses a policy mark-up language to define Enterprise Privacy Policies, which determine appropriate data handling.     

Carbon monoxide poisoning in the automobile--suicide or accident?

In cases of CO-poisoning in vehicles accidents have to be reviewed. Old automobiles or untypical discovery without manipulations have circumstantial evidence. This proceeding is demonstrated by two casuistries. The argumatative force of the first appearance is not sufficient to give reasons for private-law consequences.     

Survived crossbow injuries

The Hamburg University Institute of Legal Medicine presents 2 cases of injuries of crossbow arrows where the patients survived. Crossbows are used nowadays as sports and hunting weapons. They are freely obtainable, and since people without practice can shoot them, there are constant injuries and fatal cases. Crossbow arrows have a high penetration force and can even pierce bone. Depending on the tip of the arrow used, they bore or cut through tissue, here damage to the tissue being restricted to the direct surroundings. Due to the elasticity of the tissue, the arrow shaft in the wound track may have the effect of an incomplete tamponade so that major hemorrhaging is prevented. In this condition, the injured person may be conscious and capacitated. From the medical viewpoint, crossbow arrows should therefore be invariably left in the wound, secured against displacement during transport, and only removed in the hospital.     

Fatal and non-fatal injuries caused by crossbows

Today in modern times, traumatic injuries caused by crossbows are a rarity. The largest collection of cases so far is presented in this study, consisting of four fatalities (two homicides and two suicides) and two non-fatal injuries (grievous bodily harm and an accident). All the victims were male having an age between 31 and 54. The weapons, which were used, were mainly high-performance precision crossbows with telescopic sights and hunting bolts. The parts of the body involved were the facial/head area in three of the cases and the thorax in three of them. There were either deep or total penetration injuries to the cranium and thorax with the bolt remaining in the wound in four out of six cases. The persons with non-fatal crossbow injuries exhibited comparatively few symptoms, despite the sometimes extensive involvement of the interior of the cranium (cerebrocranial penetration, in one instance). The two cases of suicide favoured the body areas often found with gun-users. The aetiological classification of crossbow injuries may be difficult after the removal of the bolt. The external morphology is strongly dependent on the type of tip used. Multiple-bladed hunting broadheads produce radiating incised wounds, whereas conical field tips produce circular to slitlike defects. Correspondingly, the external injuries can be reminiscent of the effects of a violent attack by sharp force or of a gunshot wound. The possibility, supported by clinical data, that the victim might have the ability to act or even to survive for a period of time, even with penetration of the brain, should be taken into account when the cause of death is being investigated.     

Fatal aviation accidents in Lower Saxony from 1979 to 1996

So far no national or regional studies have been published in Germany regarding the number of fatal aviation accidents and results of autopsy findings. Therefore, we evaluated all fatal aviation accidents occurring in Lower Saxony from 1979 to 1996. A total of 96 aviation accidents occurred in this period involving 73 aeroplanes. The crashes resulted in the death of 154 people ranging in age from 19 to 68 years. The greatest number of victims in a single crash of an aircraft was (n=7). Other types of fatal accidents were crashes of aircraft and helicopter while on the ground (n=5), hot-air balloons (n=2), parachutes (n=10), hang glider accidents (n=5) and the striking of a bystander by a model airplane. Autopsies were performed on 68 of the 154 victims (44.2%), including 39 of the 73 pilots (53.4%). Some of the autopsies yielded findings relevant to the cause of the accident: gunshot wounds, the presence of alcohol or drugs in blood and preexisting diseases. Our findings emphasize the need for autopsy on all aviation accident victims, especially pilots, as this is the only reliable method to uncover all factors contributing to an accident.     

Looking for some light through the lens of “cryptowar” history: Policy options for law enforcement authorities against “going dark”

As companies and end-users increasingly deploy end-to-end encryption, law enforcement and national security agencies claim they “go dark”, i.e. lose in practice the power to legally intercept and gain access to information and communications. This has revived a debate that seemed closed by the late 1990s, namely whether backdoors should be embedded in encryption systems. This paper provides a historical overview of the policy debates surrounding encryption, to identify the potential regulatory options for policy-makers, based on the lessons that can be learned from “cryptowar” history. We discuss the First Cryptowars (1990s, focusing on backdoor schemes), the Interbellum (featuring a rise in powers to order decryption), the Second Cryptowars (2010s, renewed backdoor discussions) and their aftermath: the newly emerging battlefield of legal hacking. The latter can be seen as a condition for the truce with which – for now – the Cryptowars seem to have ended. Cryptowar history teaches us that the two main policy options for decryption by government agencies – ensuring access to keys ex ante (backdoors) or ex post (decryption orders) – both suffer from fundamental flaws. Therefore, legal hacking powers – if human rights standards are sufficiently taken into account – could be the only realistic policy option to preserve some light in an era of dark communication channels.
