The reason I got to know many professional killers first hand was because I have worked for a long time as a financial journalist. It does not take long reporting in that field before you understand finance is intimately connected with high level organized crime. As a result, in order to provide readers with the truth, it becomes necessary to cultivate sources within organized crime syndicates. As a general rule gangsters do not talk to reporters so, it took a while to assure them I was just a chronicler and not a cop and that I would not write anything that would personally incriminate my sources.
So it came to be that I started hearing many stories about the underworld, especially in Japan. Thus this week I will relate some of what I heard about real world professional killers.
