Perhaps not, but I don't think it's unreasonable to ask for a risk premium in your compensation. If you're more likely to die or be critically injured earlier than someone else of the same age solely because of the work you do, and your family depends on your income, it's not unreasonable to expect to be paid more to make up for the lost expected lifetime income.
(This is true for all dangerous professions, BTW - not just law enforcement and medical personnel.)
