For 15 years, a man named Robert Legg will be limited to a single, personal Internet-capable device and must be prepared for random government monitoring of his computer use. Legg can only have a computer if the U.S. Probation Office first gives him approval.

The technological restraints imposed against Legg, convicted in an online child exploitation sting, are at the center of a case in the U.S. Court of Appeals for the D.C. Circuit. Legg is serving a 30-month prison sentence. His lawyer on Monday urged the appeals court to find that the restrictions go too far.
