A wiretap is a method used to monitor and intercept telephone conversations or electronic communications. Law enforcement agencies often employ wiretaps to gather evidence in criminal investigations, typically requiring a court order to ensure legality. This technique can also apply to internet communications, allowing authorities to track online activities. Wiretapping can raise privacy concerns, as it involves listening to private conversations without the consent of the parties involved. In many countries, laws regulate wiretapping to protect individuals' rights, balancing the need for security with the right to privacy.
