What role do animals play in law enforcement? In a way of law enforcement I have only heard about dogs. And I know two ways how dogs can help the police. Dogs can look for something because of their sensible nose. It can be drugs or kind of exlposive things. Also dogs can catch criminals, who are trying to escape from the law.They can do it because they are faster then people and they have good teeth. Yes. If I would be a criminal I would not wanted to have a deal with a police dog. They only can not shoot from the guns, so the criminal can shoot it. If he can't then the dog will win =) Oh I've just remembered another animal - horses. I heard that police officers in New York use them to patrol streets and other places. I am not sure why do they do so. Maybe it is good to patrol big parks where you can't drive and you should have an opportunity to move fast if needed. Let me know, if you know any other animals used in law enforcement.
