What signifies the failure of traditional investigative methods in the context of wiretap authorization?

The significance of the unlikeliness of success in traditional investigative methods is central to the wiretap authorization process. In the context of wiretap requests, law enforcement agencies must demonstrate that conventional approaches, such as physical surveillance or use of informants, have proven ineffective or are unlikely to yield the necessary evidence for a case. This requirement serves to ensure that wiretaps, which involve considerable invasion of privacy, are justified and used only when absolutely necessary.

When traditional methods are assessed as unlikely to succeed, it indicates that there are significant barriers to gathering information that could otherwise be obtained through less intrusive means. This aligns with the legal standards set forth to protect individual rights while allowing law enforcement to pursue investigations effectively. The recognition of this unlikeliness is a crucial factor that courts evaluate when deciding whether to grant wiretap authorization, as they must weigh the need for the investigation against the potential intrusion into personal privacy.

The other options—plans to cause harm, notification of intent, and the presence of multiple subjects—do not directly address the limitations of traditional investigative methods in securing sufficient evidence, which is essential for warranting the use of wiretaps. Thus, the focus on the unlikeliness of success underlines an essential threshold that must be crossed to
