Dr. Sharon Lambert:

They are usually under stress. It might be stress from within their own gang. Often, they are under pressure themselves and this situation has emerged from that. The reality is that most of those who are involved in those situations do not expect to live very long. I have spoken to people who have been involved in gangland violence. It is really sad to meet an 18-year-old or 19-year-old who does not imagine that they will ever reach 30 because they will be dead by the time they are 25. That is not a brain that is thinking rationally. There is no long-term thinking there. They have no expectations for their future, in that they expect to be dead by the time they are 25.
