A helpful reader let me know that there was a new decision out of the District of Massachusetts finding the federal civil commitment scheme for sex offenders under the Adam Walsh Act was unconstitutional. You can read the opinion here. From the opinion:
The decision is notable because it creates a district court conflict in the 1st Circuit. However, the recent ruling is consistent with the 4th Circuit's opinion in Comstock (which I think had the better side of the argument).
