It seems the Ameican Civil Liberties Union continues to cherry-pick which rights they find defensible and which they don’t:
The ACLU interprets the Second Amendment as a collective right. Therefore, we disagree with the Supreme Court’s decision in D.C. v. Heller. While the decision is a significant and historic reinterpretation of the right to keep and bear arms, the decision leaves many important questions unanswered that will have to be resolved in future litigation, including what regulations are permissible, and which weapons are embraced by the Second Amendment right that the Court has now recognized.
This is pretty strange for an organization that claims absolutism for other enumerated rights, as well as seeking clemency for convicted murderers and sex offenders.
It’s somewhat ironic that the logistic problems inherent in the Iowa law closely mirror the geographical problems of the Gun-Free School Zones Act.
