Legal Definition of wiretapping
: interception of the contents of communication through a secret connection to the telephone line of one whose conversations are to be monitored usually for purposes of criminal investigation by law enforcement officers
Additional Notes on wiretapping
Wiretapping and wiretap evidence are strictly regulated under federal and state laws. An order authorizing wiretapping may be issued only when there is probable cause to believe that a person is committing, has committed, or is about to commit a particular offense, and there must be probable cause to believe that communications relating to such an offense will be obtained. Wiretapping must not be employed when a conversation is privileged, and officers must minimize interception of conversations that are not material to the investigation.
