The third alternative is correct: a contrast between different types of crime
In this text, the authors present a contrast between two types of crime: white-collar crimes and common crimes.
White-collar crimes are financial crimes, such as corruption. This type of crime affects all of society in a proportional way, so that there is no specific victim, all are victims. This type of crime is done in a silent and hidden way, so that its discovery demands regulation and investigation.
Common crimes are considered assaults and murders. These crimes affect a specific person, who feels extremely injured and makes a complaint, which leads to a greater social perception of this type of crime in relation to white collar crime.
