Shoplifting (also known as shop theft, retail theft, or retail fraud) is the theft of goods from a retail establishment during business hours. The terms shoplifting and shoplifter are not usually defined in law, and generally fall under larceny. In the retail industry, the word shrinkage (or shrink) is used to refer to merchandise often lost by shoplifting. The term five-finger discount is a euphemism for shoplifting, humorously referencing that stolen items are taken "at no cost" with the five fingers.
The first documented shoplifting started to take place in 16th century London. By the early 19th century, shoplifting was believed to be primarily a female activity. In the 1960s, shoplifting began to be redefined again, this time as a political act. Researchers divide shoplifters into two categories: boosters (professionals who resell what they steal), and snitches (amateurs who steal for their personal use).[1]
Shoplifters range from amateurs acting on impulse to career criminals who habitually engage in shoplifting as a form of income. Career criminals may use several individuals to shoplift, with some participants distracting store employees while another participant steals items. Amateurs typically steal products for personal use, while career criminals generally steal items to resell them in the underground economy. Other forms of shoplifting include swapping price labels of different items, return fraud, or consuming food and drink at a grocery store without paying for it. Commonly shoplifted items are those with a high price in proportion to their size, such as disposable razor blades, electronic devices, vitamins, alcoholic beverages, and cigarettes.
Stores use a number of strategies to reduce shoplifting, including storing small, expensive items in locked glass cases; chaining or otherwise attaching items (particularly expensive ones) to shelves or clothes racks; attaching magnetic or radio sensors or dyepacks to items; installing curved mirrors mounted above shelves or video cameras and video monitors, hiring plainclothes store detectives and security guards, and banning the bringing in of backpacks or other bags. Some stores have security guards at the exit, who search backpacks and bags and check receipts. Stores also combat shoplifting by training employees how to detect potential shoplifters.
