"When a sex offender moves out of the country, does he have to tell anyone?"

Evan Lee (Hastings) has this post at ScotusBlog, previewing tomorrow's oral argument. In part:

The government’s chances thus seem to depend upon the Court’s receptiveness to the assertion that the purpose behind SORNA is to create a system that keeps track of sex offenders in every conceivable way, including when they are no longer in the United States. Not only must the Justices accept that premise, but they must agree that the Court is the appropriate body to fill out a statute that does not address the issue in so many words. The empty seat of the late Justice Antonin Scalia will undoubtedly catch the corner of every eye as this classic case of statutory interpretation is debated.
