 This account differs from the previous ones in two important ways. First, although one might justify quarantine (in the case of disease) and incapacitation (in the case of dangerous criminals) on purely utilitarian or consequentialist grounds, Pereboom and Caruso resist this strategy. The incapacitation of dangerous criminals is instead justified on the ground of the right to harm in self defense and defense of others—a right that arguably has broader appeal than consequentialism. They contend that this justification makes the view more resilient to objections, especially the use-objection mentioned above (Pereboom 2017a). This is because, as it is illegitimate to treat carriers of a disease more harmfully than is necessary to neutralize the danger they pose, treating those with violent criminal tendencies more harshly than is required to protect society will be illegitimate as well. Furthermore, innocent people could not be incapacitated on this account since they pose no direct threat to others.
