 Inquiry into the ethics of suicide prevention should also take stock of variations in when preventive actions occur and how carefully targeted they are. Some preventive actions, such as the short-term institutionalization of suicidal persons, are undertaken in clinical or criminal justice settings, whereas other preventive actions (such as calls to suicide hotlines) occur at greater distance from the suicidal individual. These different settings raise different ethical concerns about individual rights, privacy, and autonomy, as well as concerns trust and honesty. (On ethical questions related to suicide hotlines, see Martin 2011.) Still other preventive actions (restricting legal access to firearms or household poisons often used in suicide, or adding lithium to drinking water supplies to reduce the incidence of suicidal emotions) occur at a population level, thus raising concerns not only about their efficacy but about the risks posed to the non-suicidal individuals’ well-being and rights.
