Which statement about investigative surveillance is not true?

Investigative surveillance is a critical tool used in security and investigative operations, and understanding the nature of its legality is essential. It's important to recognize that while investigative surveillance can be complex and subject to various laws and regulations, it is not inherently illegal in most jurisdictions. In fact, many forms of surveillance are legally permissible when conducted in accordance with established laws, such as obtaining necessary permissions, respecting privacy rights, and adhering to jurisdiction-specific regulations.

Law enforcement and private investigators often utilize surveillance techniques as part of their investigative procedures, provided they operate within the framework of the law. The legalities surrounding surveillance can vary significantly; some types may require a warrant, while others might necessitate notification of the parties being surveilled. This allows for responsible and lawful use of surveillance in protecting property and ensuring safety.

In contrast, investigative surveillance is typically recognized as being expensive, time-consuming, and sometimes nonproductive due to the inherent challenges in gathering information or confirming suspicions. These aspects are realistic considerations for entities employing surveillance methods, making the statement about legality the outlier among the options.
