A "Tip Line" is a dedicated phone number or online service that allows individuals to report information about criminal activity or suspicious behavior. These lines are often managed by law enforcement agencies, such as the FBI or local police departments, to gather tips from the public that may assist in ongoing investigations. Tip lines can be anonymous, encouraging people to share information without fear of retaliation. They play a crucial role in community safety by enabling citizens to contribute to crime prevention and resolution efforts, ultimately helping to keep neighborhoods safer.
