The information age has created plenty of extra convenience, but officials say it has also created lots of dangers, especially for teenagers.

Kids don't need a license, and certainly don't have to wait till they're 16, to get on the information superhighway.

Paul Iannance has spent the past decade and a half investigating computer crimes for the Pennsylvania State Police.

First there's the issue of cyber-bullying which made national headlines when a 13 year-old Missouri teen committed suicide.

But the biggest problem cops now see?

"Sexting," Iannace says. " How does it work? 

Iannace says, "Boy dates a girl, he convinces her to take a picture -- nude, semi-nude. She sends it to him they break up, where does the picture end up?"

In the case of Emmaus High School students, the photos ended up on a foreign website for anyone to see.

And plenty of classmates did.

"Sexting" isn't just dangerous --  it can actually send kids to jail. 

"According to Pennsylvania law right now, those two produced child pornography, they disseminated child pornography because they exchanged it, and yes, they would be in possession of child pornography.   All three are felonies, really really serious crime," says Iannace.

But Iannace says it's not just kids who need to beware. If an adult texts a nude picture to someone, it's not a crime for them to post it. But that person can be sued for invasion of privacy.

As Iannace notes, "You put something on the web, it's there forever."

And as some teens have found out the hard way, 'forever' is a very long time.
