The most obvious obstacle to winning a Third Amendment claim here is that police arguably do not qualify as “soldiers.” On the other hand, as Radley Balko describes in his excellent new book The Rise of the Warrior Cop, many police departments are increasingly using military-style tactics and equipment, often including the aggressive use of force against innocent people who get in the way of their plans. If the plaintiffs’ complaint is accurate, this appears to be an example of that trend. In jurisdictions where the police have become increasingly militarized, perhaps the courts should treat them as “soldiers” for Third Amendment purposes.

A second possible impediment to winning a Third Amendment claim in this case is that the Amendment is one of the few parts of the bill of rights that the Supreme Court still has not “incorporated” against state governments. For incorporation purposes, claims against local governments (like this one) are treated the same way as claims against states. On the other hand, the Supreme Court has never ruled that the Third Amendment does not apply to the states. If, as the Court has previously decided, virtually all the rest of the Bill of Rights applies to state governments, there is no good reason to exclude the Third Amendment. If the Third Amendment part of the case is not dismissed on other grounds, the federal district court may have to address the issue of incorporation.
