 There is much room for philosophical exploration of these issues. One area that merits attention is the definitions of key terms, such as “safety” and “risk”. Drop side cribs pose risks to consumers; so do trampolines. On what basis should the former be prohibited but the latter not be (Hasnas 2010)? The answer must take into account the value of these products, how obvious the risks they pose are, and the availability of substitutes. With respect to liability, we may wonder whether it is fair to hold manufacturers responsible for harms their products cause, when the manufacturers are not morally at fault for those harms. On the other hand, it may be unfair to force consumers to bear the full costs of their injuries, when they too are not morally at fault. The question may be one for society as a whole: what is the most efficient or just way to distribute these costs?
