It's always a tragedy when you hear of somebody who gets involved in an altercation with police with a tragic outcome or of someone who somehow seems to have gone off the rails somewhere.
I think you have to be conscious that we don't cure everybody, particularly when it comes to mental health care. Generally, what you're trying to do is help people cope with their conditions on a chronic basis. You'll find that it's not linear. It's not like it's worse and then it gets better in a linear way. Sometimes people have relapses. Even with the best treatment for things like PTSD, if you search the literature and sort of take an average figure of how many people are helped by treatment and how many people are not, you'll get a split of about two-thirds who are helped and one-third who are not, even with the best available treatment. So you can mobilize a lot of resources and there will still be some people who unfortunately don't do well.
