By now, all parents should be well aware of the potential dangers of cyberbullying and Internet predators on social networking sites. But social networking can also keep our kids safe in ways previously unavailable. Law enforcement is discovering how to use Facebook and MySpace as a way to identify, prevent, and protect kids from crimes.

Many police departments now have a presence on Facebook or MySpace. By using social networking to establish a relationship with the community, police can reach out to at-risk youth and provide a teen-friendly avenue for reporting dangerous or illegal activity.

This can be a convenient way to relay messages, but it can also be dangerous if your child isn’t aware of who can see their pictures (and the captions they tack on them.)
