California v. Greenwood - 1988
issue: whether the 4th amendment prohibits the warrantless search and seizure of garbage left for collection outside the home, outside the curtilage?
holding: a person has no reasonable expectation of privacy in garbage in an enclosed bag and left for collection outside the curtilage of a home. No search occurs, therefore, when a PO opens a trash bag left at the curb and sifts through it’s contents without a warrant
- fails on the second prong of Katz
- when you put it out there for public consumption, you have to expect all sort of people and animals might come by and one of them might be a police officer
Florida v. Riley - 1989
is there a privacy interest in the airspace above the curtilage of a house?
no, so long as PO is in a place where the public can be, he’s good. No PC or warrant required

exception: if the PO is in a place where he is likely to cause danger to people or property (ex. flying helicopter at 50 feet above curtilage) then this is a search and PC or warrant is required
