Hitmen

Contract killing is a form of murder in which one party hires another party to kill a target individual or group of people. It involves an illegal agreement between two or more parties in which one party agrees to kill the target in exchange for some form of payment, monetary or otherwise. Either party may be a person, group, or an organization. Contract killing has been associated with organized crime and with vendettas. For example, in the United States, the gang Murder, Inc. committed hundreds of murders on behalf of the National Crime Syndicate during the 1930s and 1940s.

Contract killing provides the hiring party with the advantage of not having to commit the actual killing, making it more difficult for law enforcement to connect said party with the murder. The likelihood the authorities will establish that party's guilt for the committed crime, especially due to lack of forensic evidence linked to the contracting party, makes the case more difficult to attribute to the hiring party.

In the United States, the United Kingdom, and many other countries, a contract to kill a person is void, meaning that it is not legally enforceable. Any contract to commit an indictable offense is not enforceable under contract law. Thus, if a "hitman" takes the money but then fails or refuses to perform, the customer (or hiring partner) cannot sue for specific performance or for damages for breach of contract. Conversely, if the hitman performs the killing as promised but the customer refuses to pay, the hitman cannot sue the customer for monetary damages. Furthermore, both the actual killer and the person who paid the killer can be found guilty of murder. Indeed, the acts of merely negotiating and paying for a contract killing (that is never actually carried out) are themselves punishable as attempted murder, as they constitute the "substantial step" towards a crime that is essential for imposing liability for an attempted crime. In some U.S. jurisdictions with capital punishment, a contract killing may be a special circumstance that allows for the contractor as well as the killer to receive the death penalty. Criminal code statutes prohibiting "solicitation of murder" are also intended to curb contract killings.
