It is really not that surprising that a police officer stole bitcoins. Anyone can turn out to be bad guys but if you think that police officers are innocent country-loving servants then you are mistaken. A lot of police officers even turn out to be the most corrupt and most evil of the bunch. They usually are the root of the problem. Also if it is a low ranking official, I am not surprised if he needed money and he had to get it by stealing. It is ironic but not surprising. Everyone can see that bitcoin is a very profitable industry so even those who do not know much about it wants to profit off of it.
