Deaths in isolation as prison segregation increases
The use of segregation of prisoners as punishment has been increasing recently in Australia, the US, and the UK. Segregation can be used for protection or punishment, but in both cases it results in extreme psychological stress. An indication that segregation is being over-used is the appearance of deaths in custody from suicide of those placed in segregation.
