The Cardozo Law Review de novo online journal just published my essay entitled "The Potentially Expansive Reach of McDonald v. Chicago: Enabling the Privileges or Immunities Clause," in a feature it entitles "Firearms, Inc." The essay may be seen here.
The essay briefly reviews the sad history of how the Supreme Court buried the Privileges or Immunities clause in 1873, just five years after its birth; then offers a possible doctrinal approach were the Court to move forward in finally giving proper effect to the Privileges or Immunities clause.
