I don't have specific knowledge of all the processes related to homicides and suicides. The process is indeed different in the case of a suicidal person. The fact remains that the person is experiencing acute suffering. However, insofar as statistics are concerned, I think there is a certain stability. The difference is that there is now more media attention focused on the phenomenon.
