Theft

Theft (from Old English þeofð, cognate to thief) is the act of taking another person's property or services without that person's permission or consent with the intent to deprive the rightful owner of it. The word theft is also used as a synonym or informal shorthand term for some crimes against property, such as larceny, robbery[heist], embezzlement, extortion, blackmail, or receiving stolen property. In some jurisdictions, theft is considered to be synonymous with larceny, while in others, theft is defined more narrowly. A person who engages in theft is known as a thief (pl. thieves).

Theft is the name of a statutory offence in California, Canada, England and Wales, Hong Kong, Northern Ireland, the Republic of Ireland, and the Australian states of South Australia and Victoria.

The actus reus of theft is usually defined as an unauthorised taking, keeping, or using of another's property which must be accompanied by a mens rea of dishonesty and the intent to permanently deprive the owner or rightful possessor of that property or its use.

For example, if X goes to a restaurant and, by mistake, takes Y's scarf instead of her own, she has physically deprived Y of the use of the property (which is the actus reus) but the mistake prevents X from forming the mens rea (i.e., because she believes that she is the owner, she is not dishonest and does not intend to deprive the "owner" of it) so no crime has been committed at this point. But if she realises the mistake when she gets home and could return the scarf to Y, she will steal the scarf if she dishonestly keeps it (see theft by finding). Note that there may be civil liability for the torts of trespass to chattels or conversion in either eventuality.

Possible causes for acts of theft include both economic and non-economic motivations. For example, an act of theft may be a response to the offender's feelings of anger, grief, depression, anxiety, compulsion, boredom, power and control issues, low self-esteem, a sense of entitlement, an effort to conform or fit in with a peer group, or rebellion. Theft from work may be attributed to factors that include greed, perceptions of economic need, support of a drug addiction, a response to or revenge for work-related issues, rationalisation that the act is not actually one of stealing, response to opportunistic temptation, or the same emotional issues that may be involved in any other act of theft. Grotius and Pufendorf upheld the principle that a person in extreme and unavoidable need, who took from the surpluses of property holders, was not guilty of the crime of theft.

The most common reasons for shoplifting include participation in an organised shoplifting ring, opportunistic theft, compulsive acts of theft, thrill-seeking, and theft due to need. Studies focusing on shoplifting by teenagers suggest that minors shoplift for reasons including the novelty of the experience, peer pressure, the desire to obtain goods that a minor cannot legally purchase, and for economic reasons, as well as self-indulgence and rebellion against parents.

In Buddhism, one of the five precepts prohibits theft, and involves the intention to steal what one perceives as not belonging to oneself ("what is not given") and acting successfully upon that intention. The severity of the act of theft is judged by the worth of the owner and the worth of that which is stolen. Underhand dealings, fraud, cheating and forgery are also included in this precept. Professions that are seen to violate the precept against theft are working in the gambling industry or marketing products that are not actually required for the customer.

The Manusmriti and the Dharmashastras deal with theft, coveting wealth, and punishment for these.
