Police killings of individuals with mental illness have prompted calls for greater funding of mental health services to shift responsibilities away from the police. Such investments can reduce police interactions with vulnerable populations but are unlikely to eliminate them entirely, particularly in cases where individuals with mental illness have a weapon or are otherwise dangerous. It remains a pressing question, then, how police should respond to these and other vulnerable aggressors with diminished culpability (VADCs). This article considers and ultimately rejects (...) three potential approaches from the ethics of defensive force literature. It looks to improve on them by developing what I call the fusion account, which explains how vulnerability and diminished culpability fit together to provide moral grounds for extra protections from deadly force. The article’s final sections explore the policy implications of the fusion account for police administrators, officers, and the law. (shrink)

Measures aimed at general deterrence are often thought to be problematic on the basis that they violate the Kantian prohibition against sacrificing the interests of some as a means of securing a greater good. But even if this looks like a weak objection because deterrence can be justified as a form of societal self-defence, such measures may be regarded as problematic for another reason: Harming in self-defence is only justified when it’s necessary, i.e., when there are no relatively harmless alternatives. (...) While there are few harmless ways to remove the threat posed by dangerous individuals, there are many relatively harmless methods for preventing crime. We can bracket off our preventative failings when we think of present threats, but we cannot do so when contemplating alternative preventative measures. (shrink)

The Animal Rights Thesis (ART) entails that nonhuman animals like pigs and cows have moral rights, including rights not to be unjustly harmed. If ART is true, it appears to imply the permissibility of killing ranchers, farmers, and zookeepers in defense of animals who will otherwise be unjustly killed. This is the Militancy Objection (MO) to ART. I consider four replies to MO and reject three of them. First, MO fails because animals lack rights, or lack rights of sufficient strength (...) to justify other-defensive killing. Second, MO fails because those who unjustly threaten animals aren't liable or, if they are liable, their liability is outweighed by other considerations (e.g., a strong presumption against vigilante killing). I then argue both of these fail. Third, MO succeeds because animal militancy is permissible. Fourth, MO fails because there aren't liability justifications for defensive killing in general (i.e., pacifism is true). I argue that there's thoroughgoing epistemic parity between the Militancy View (MV) and the Pacifist View (PV), and that two considerations favor PV over MV. First, because under conditions of uncertainty, we should believe rights-bearers retain rather than lose their rights, which PV affirms and MV denies. Second, because PV is intrinsically likelier than MV to be true since PV at worst affirms wrongful letting die and MV at worst affirms wrongful killing, the latter of which is intrinsically harder to justify than the former.

In a very short article, James Sterba argues that there is a moral duty to sacrifice one’s life to save the lives of others. Sterba justifies this duty by drawing an analogy with a series of cases in which some degree of sacrifice would be commonly accepted for the benefit of third parties. In this paper, I argue that Sterba’s argument reaches the correct conclusion, but is invalid. In addition, I point out two different arguments to support the existence of (...) a duty to sacrifice one’s life to save the lives of others. (shrink)
