Ethnography and Voyeurism

As I've now completed my fieldwork in prison, it's good to reflect upon the experience. The ethical tensions of prison ethnography cannot be ignored, and this has come up in discussions over the last couple of days with academics and other doctoral candidates. Is prison ethnography inherently coercive and voyeuristic? Or does it represent an opportunity for researchers to be the ears and eyes that can reveal a world inaccessible to most? More stuff to contemplate.
