I'm no dane, but we had a shooting episode last weekend, going against a gay bar in Oslo.
As far as I know it was paranoid schizophrenia with the guy in Oslo, and as far as I know this young man in Copenhagen also is a similar case. If it is, its the third case of psychiatry going nuts and killing people in the last 6 months. I don't know the Danish health care system, but I have worked in an organisation here in Norway who works for youth and young adults mental health, and I've seen that our system with way to long periods of waiting are not working. And that is for younger people. It's even longer if you are over 25. For me, this is just as much a cry for help in regards to psychological help, and that it needs to be a focus. (Just taking a chance and guessing that Denmark are also having similar issues as we do, only that they are a smaller country with twice as many people as we have...)
