Another name for a “rape kit” is “evidence.” It’s the sort of stuff police use to investigate crimes. With pretty much all other crimes, the state pays for whatever work had to be done to get the evidence together. For example: we don’t expect murder victims’ families to pay for autopsies. No, the state pays the Medical Examiner’s salary so they can figure out how someone died. In some parts of the country, however, rape victims are expected to foot the bill for evidence to be gathered.
