Editor's Notes

  1. Virginia Declaration of Rights – 1776 “That general warrants, whereby any officer or messenger may be commanded to search suspected places without evidence of a fact committed, or to seize any person or persons not named, or whose offense is not particularly described and supported by evidence, are grievous and oppressive and ought not to be granted.”
  2. Who does it apply to? Right of the people, not person. Significance? Focus on the government’s actions, rather than remedies of individ What does it apply to? Persons, houses, papers, and effects What is the government forbidden to do? Conduct unreasonable searches and seizures Are warrants required? No Searches just must be reasonable But if warrants are issued, what must they be based on? Probable cause And how must the warrants be crafted, if issued? Particularly describing the place or person or thing to be searched
  3. “The right of the people to be secure … against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause” Textualist interpretation Search must be reasonable warrant clause only applies when warrant sought Supreme Court Interpretation Search without warrant presumptively unreasonable Unless warrant exception met
