If there's a safety issue, there are many interventions. The problem with segregation is that it's a 23-hour lock-up in conditions of deprivation, which are the most austere conditions the Correctional Service has. If people are at significant risk of self-harm, you may also put them on suicide watch. You may put them under direct observation. You may increase the frequency of security rounds for the cell they're in. You may move them into a hospital or health care setting. You may transfer them to an outside hospital. You may put them into one of those regional treatment centre beds we were talking about. There are lots of other options.
Unfortunately, what we see is this cycle. People act out. The behaviour is dealt with, but not the underlying cause. The acting out causes them to be segregated as an administrative or punitive measure to deal with their acting out behaviour. The underlying cause is not dealt with. It doesn't do anything to deal with the behaviour. That's what happened to Ashley Smith for 11 and a half months.
