Another particularly risky study was undertaken by Laud Humphrey's "Tearoom Trade" (1975) whereby he not only subjected himself to personal danger and compromise, (arrested several times), he also ran the risk of breaching ethical standards by violating the participants rights to privacy. This high-risk method of research is inevitably employed into studies of criminal or sensitive issues.
