Going through the guy's 'CV' from the article, I guess one of the reasons the authorities never went "all the way to 11" to catch him, is that the harm he did was relatively 'small' - meaning of financial nature - he didn't physically hurt/murdered anyone. (I am not OK-ing what he did, I just think that if you got 100 killers out and about please catch them and the $200k guy will be caught sooner or later by some bureaucratic control).
