When a man is arrested and convicted of rape, he is known as a rapist and a sex offender. When an individual is convicted of distributing narcotics, he is known as a drug dealer. However, what a person is arrested for constitutes, in most instances, the tip of the iceberg. In more than 40 years of interviewing offenders, every rapist whom I have interviewed has committed crimes other than rape -- e.g., nonsexual assaults, theft. Even typing a person as a "white collar" offender may not be accurate. I have interviewed white-collar individuals who have committed acts of domestic violence, alcohol abuse, and drug abuse.
It is true that offenders have tastes and preferences in crime. The white-collar offender looks down on the violent street criminal as crude and as sharing nothing in common with him. The guy who resorts to force ("muscle") may look down on someone not so inclined as "sissy," "lame," or "weak."
