In law enforcement, a manhunt is an extensive and thorough search for a wanted and dangerous fugitive involving the use of police units, technology, and help from the public.
Law enforcement is any system by which some members of society act in an organized manner to enforce the law by discovering, deterring, rehabilitating, or punishing people who violate the rules and norms governing that society.
A fugitive is a person who is fleeing from custody, whether it be from jail, a government arrest, government or non-government questioning, vigilante violence, or outraged private individuals.
