In corrupt practices, officials behave cautiously, carefully concealing their crimes, for example, by registering shell companies in the name of their friends. In this scheme, it is far from always possible to establish relations between people. As part of a criminal case, law enforcement officers gain access to information about joint trips abroad, telephone conversations, previous jobs, and much more. It is difficult to manually analyze such an array of data, which is why analytics tools are of great assitance.
