Blackmail is the crime of threatening to reveal substantially true information about a person to the public, a family member, or associates unless a demand made upon the victim is met. This information is usually of an embarrassing and/or socially damaging nature. As the information is substantially true, the act of revealing the information may not be criminal in its own right nor amount to a civil law
defamation; the crime is making demands to withhold it.
Blackmail is similar to
extortion—the difference being that extortion involves an underlying, independent criminal act, while blackmail does not.
The word is derived from the word for tribute paid by English and Scottish border dwellers to
Border Reiversin return for immunity from raids. This tribute was paid in goods or labour ("reditus nigri", or "blackmail"): the opposite is "blanche firmes" or "reditus albi", or "white rent" (denoting payment by silver).
Under section21(1) of the
Theft Act 1968of English law, a person commits the offence::if, with a view to gain for himself or another or with intent to cause loss to another, he makes any unwarranted demand with menaces; and for this purpose a demand with menaces is unwarranted unless the person making it does so in the belief:::(a) that he has reasonable grounds for making the demand; and::(b) that the use of the menaces is a proper means of reinforcing the demand.The Act uses the word "menaces" which is considered wider in scope than "threat" and involves a warning of any consequences known to be considered unpleasant by the intended victim. This covers the spectrum from actual or threatened violenceto the victim or others, through damage to property, to the disclosure of information.
Pretexts for blackmail have included the threat to reveal
adulteryor criminal acts. But whatever the nature of the menace, it must be direct. Any vague threat to cause "something bad" to happen to some other person, except when certain demands are met, should not affect the mind of an ordinary person.
Commercial blackmail has become more common. This arises when a large commercial organisation receives credible information that it will suffer loss or damage in a particular way unless money is transferred. There are two major areas of threat:
denial of service attacks target corporations that have a major presence on the internet. Disrupting the portal through which on-line sales are made could seriously affect the corporation's revenue flow and demonstrating an ability to orchestrate consistent attacks may well represent a sufficient menace for these purposes; and
poisons or other dangerous chemicals into the products offered for sale in a supermarketor other large store could significantly damage retail sales, or influence a manufacturer or national distributor. For example, a blackmailer threatened Masterfoods Corporation, the company that manufactures Mars Bars in Australia, claiming to have poisoned seven Mars and Snickers bars at random in New South Wales.(See also protection racket.)
Debt collectors have been accused of blackmail, but those pursuing legal debts are generally able to justify their threats of repossession because, even though as it may be unpleasant to the victim, this is a legitimate use of lawful civil law remedies.By contrast, those chasing
illegal debts(a gambling debt, for example, which was not until recently enforceable under English law)Fact|date=October 2007 who back up their demands with the threat of bodily injury cannot avail themselves of the same defence. There will also be liability even though the debts are legally owed if the menaces are of a criminal nature, e.g. of an assaultor more serious violence or criminal damage occurred.The offence criminalises the means adopted by the creditors as the social problem to be deterred, rather than the evasion by the debtors. The creditors are expected to use the standard judicial remedies to recover what is owingFact|date=October 2007.
The maximum sentence under the terms of the Act is life imprisonment; this reflects the severity of the offense, which in turn, can consequently destroy a person's reputation, personal life and livelihood.
