Here's the hard part:
Could you spot an abductor on the street? Could you tell which person in a crowd is a kidnapper? Unfortunately, kidnappers don't always look or act differently. They may try to give you candy or presents and offer to be your friend. Just remember that they could harm you.
The good news is that most kids or young adults who are abducted are returned home safely. If one of your friends was ever taken, know that they have a team of the toughest, most intelligent and resourceful law enforcement personnel trying to find them: the police. The FBI helps the local and state police investigate the kidnapping.
Remember that child abduction is very rare. However, it is important to use your good sense in all situations.
