I can guarantee you all, that folks in the military and LEO professions each know at least one person who would go postal or commit suicide if he felt cornered, rightly or wrongly and lost everything important to them. Sometimes, or most of the time, it's due to the person's own fault, sometimes it's not. It's impossible to know beforehand.
I sure hope this guy is put down before he takes any more lives.
