The terms extortion and blackmail are often used interchangeably, although there are differences. Extortion is the illegal and intentional use of threats to ones person or property, coercion, or fraudulent claims of right of public duty (such as impersonating a police officer) for the purpose of taking money, goods, property, services or some other thing of value from a victim against his/her will. These threats can be those of violence, physical harm, criminal prosecution, or public exposure of harmful or secret information that would damage a persons reputation and/or standing in the community. When the threat is to reveal embarrassing, harmful, and/or shameful information about the victim to his/her friends, co-workers, associates, family members or to the public in general, this is generally defined as blackmail, and is usually considered a type of extortion.
