The quest for that sweet spot dates from the early 17th century and the “castle doctrine” of English common law, which protected residents from unannounced government intrusions. That ethos was enshrined in the United States Constitution in 1791 with the ratification of the Fourth Amendment, which prohibits “unreasonable searches and seizures” and requires that warrants be backed by probable cause.
