You have to also realise that a significant number of suicides, especially cutting up, are actually not genuine suicide attempts at all, but end up with death as the undesired result.
It is not at all unusual for a prisoner to cut themselves, or use the alarm call prior to suspending themselves, expecting a prompt attendance from staff and thus a rescue, unfortunately in the case of suspension, it takes a frighteningly short time to become unconscious and death may result, even if unintentional, if attendance to cell alamr is delayed for any of the million and one reasons that divert staff attention then this may the the result.
Other suicide attempts are more self harm, some prisoners feel a sense of relief when they see their own blood being let.
One case I can think of in particular, the prisoner was refferred to psychologists to address his self harm, and treatment was succesful in that the subject finally understood why he was injuring himself.
This treatment was successful, except that now he understood why he self harmed, he no longer had that avenue of relief from the pressures in his head.
He committed suicide, and it was intentional given the preparations he had made such as ensuring the cell door could not be opened quickly, note etc.
One aspect of prison suicide may seem surprising to prison outsiders, a succesful suicide attempt often leads to more copycat attempts, and without a great deal of vigilance a prison can acquire a bad reputation as a suicide jail, its almost then becomes endemic.
When people are incarcerated, problems that are minor annoyances outside, can become overwhelmingly magnified, partly because the prisoner may well not have any means to arrive at a solution, they simply get stuck in their minds with a situation and just cannot move on past it - for example one inmate recently was upset that his kit issue did not include a t-shirt that fitted him, unfortunately the clothing store was closed at the time - it being a weekend - and when a member of staff told the prisoner this, it escalated into raised voices, other prisoners joined in and suddenly we had a very dangerous situation, we very nearly lost the entire wing, all over a damned t-shirt, and was all just because the inmate couldn’t move his mind on 24 hours until Monday when he could get to the clothing store.
Its this sort of distorted reality that can lead to prisoners self-harming and committing suicide, and its a subject we have to try to be open with prisoners about, and the worry is always that mere talking about the subject may put ideas into places where they were not.
I can think of some very horrible ways that have been used for suicide, I don’t thiknk its wise to discuss them here, there is an odd sort of machismo in the minds of a few tortured souls.
