Why is there suicide prevention in prison?

That's a great question because it points out the irony. The criminal justice system does everything it can to drive a convicted person to suicide but then they have counselors in prison to prevent it. It's a perverted sense of justice. The truth of it is that most people who work inside the system feel like you do but they also know that it doesn't look good from a public perspective to have prisoners actually commit suicide. So there you have it. It's a system that intends to drive people toward suicide but which doesn't want the conclusion because it paints a negative picture of the system itself..
