Thus, for Parker ("A View From The Boys") an ethical problem was the extent to which researchers should deceive people by pretending to be "one of them". Parker, for example, chose to withhold some data from publication and discussed publication of certain information with the gang members (he left the final decision over some matters with them). His main concern was that his research did not harm gang members. This may resolve ethical problems, but raises the problem of not being able to give a full account of the behaviour studied.
