Cases of police suicides may be known to the public, but not all
of them were reported. Not that the media finds it always news
worthy too anyway. If people here are concerned about the "why"
questions, then you might as well wait for the case to be brought
to the courts, a process which will take months. Either you have to
stake out the court rooms waiting for the results, or pray that the
press bothers to publish it. If not, then please do show some basic
respect for the privacy of the perished and his family. I do find
some of the demands for information in this thread in bad
taste.
