One of the legal gimmicks invented by judges to empower the police to violate your Fourth Amendment rights is called the “ community caretaking exception.” This rule was created 48 years ago by the Supreme Court in a decision called Cady v. Dombrowski, 413 U.S. 433 (1973).

But Cady was about a car on a public road, not the home. Searches of cars have long been held to a lower standard than searches of homes.
