Constitutional law scholars have long observed that many doctrinal rules established by courts to protect constitutional rights seem to "overprotect" those rights, in the sense that they give greater protection to individuals than those rights, as abstractly understood, seem to require.' Such doctrinal rules are typically called "prophylactic" rules.2 Perhaps the most famous, or infamous, example of such a rule is Miranda v. Arizona,' in which the Supreme Court implemented the Fifth Amendment's privilege against self-incrimination4 with a detailed set of directions for law enforcement officers conducting custodial interrogations, colloquially called the Miranda warnings. 5
