Fifty-five years and older is determined for most purposes of the criminal justice system to be 'elderly.' It is apparent that although this age group's participation in crime in general and ordinary crime in particular is limited, the elderly are instrumental in carrying out professional and organized crime. In addition, their influence can be seen on white-collar crime. The age of criminals involved in white-collar and organized crime generally is older than is true for ordinary crime. Although the elderly involved in professional and organized crime may not carry out many criminal acts, they are the planners, policy setters, and leaders. The same is true for white-collar crime.
