Tampering (Crime)

Offenses Against Public Safety and State Security

Tampering can refer to many forms of sabotage, but the term is most often used for the intentional modification of products in a way that makes them harmful to consumers. The threat has led manufacturers to design products that are difficult to modify, or at least difficult to modify without revealing that tampering occurred, and because the person responsible is typically gone by the time the crime is discovered, many cases are never solved.
