What is more surprising in this news is not that the government was able to trace these transactions even after the police officer's efforts to eliminate the trace (I suppose that he made a mistake at some point) but the fact that the delinquent was a policeman. I want to believe that most police officers carry out their obligations with due diligence and, although we all know of cases in which the behavior of some departs far from what would be desirable, it is the exception and not the norm.
But, apart from the surprising figure of the protagonist in this story, this should serve as a "notice to mariners" who might be considering using Bitcoin to cover up their shady activities.
I can't tell what happens in other countries that have a reputation of law being protected but such a bad type of people have become policemen in my country that I laugh when I see them. The guy wanted to be a thief, he was smoking weed and doing lots of prohibited things and a few years later, I see him as a policeman. I don't know him personally but it's what I've heard about him and I've personally seen him with this type of people, so I'm sure he is not a good policeman. I've also seen myself how two policeman were saying that they are gonna smoke weed tonight and etc while these are the people that arrest those who smoke weed fr 8-20 years or forever. Everything is corrupted everywhere, that's my conclusion.
