this kind would justify cases of rescue and in fact make such rescue a duty even between strangers. with this justification in mind, philosopher peter singer suggests that if one saw a child drowning and could intervene to save him, they should do so, if the cost is moderate to themselves. damage to their clothing or shoes or how late it might make them for a meeting would be an insufficient excuse to avoid assistance. singer goes on to say that one should also try to rescue distant strangers, not just nearby children, because globalization has made it possible to do so. such general arguments for a duty to rescue also explain why after the 2010 haiti earthquake, haitians were digging family members, friends, and strangers out of the rubble with their bare hands and carrying injured persons to whatever medical care was available. it also explains why, journalist and physician sanjay gupta and a number of other md-journalists began acting as physicians to treat injuries rather than remaining uninvolved in their journalistic roles. similarly, they justify journalist anderson cooper's attempt to shepherd an injured young boy away from some "toughs" nearby in the aftermath of the haiti earthquake.
