Failure to identify potential psychological vulnerabilities of people
entering the Criminal Justice System continues to present a serious pr
oblem for the police and other agencies. This paper reviews some of th
e problems involved which include: the nature of the handicap itself,
current guidelines and definitions, and somewhat arbitrary legal inter
pretations by the courts. An experiment is described in which police o
fficers chose not to identify someone as vulnerable or 'at risk', desp
ite information in all conditions having been biased towards eliciting
a positive judgement.
