While Florida is tough -- and getting tougher -- on sex offenders, the U.S. Department of Justice is looking to undercut those efforts when it comes to teenagers.

A revised federal rule posted this month would let states decide whether to include teen offenders on their public registries. Current law requires all juveniles 14 and older convicted of sex crimes to register for the rest of their lives and for states to post that information publicly.

Florida currently has 113 teenagers listed on its sex-offender registry.
