There are many sources of such rules, from constitutions to laws to internal regulations to officer norms, but we will study only the top of that pyramid: the restrictions of our federal Constitution. In particular, we will study the Fourth Amendment’s protection against unreasonable search and seizure, some of the Fifth Amendment’s guarantee of due process and privilege against compulsory self-incrimination, and a bit about the Sixth Amendment’s right to counsel. Together, this is much of the constitutional law that prevents our living in a police state: anti-accuracy norms enshrined in our Constitution to protect our liberty, our humanity, and our dignity. This book is therefore also about the people—We the People—and what rights we can expect, and what rights we should expect, even as against those who are—or should be—seeking to keep us safe.
