“...may not object to a search when he is not at home.”
I didn’t read the article, but I hope this means that the occupant consents IS home that they can perform a search. (Still not right imho.)
I hope it doesn’t mean “Ok Frank, the guy just left for work - break down the door.”
“We therefore hold that an occupant who is absent due to a lawful detention or arrest stands in the same shoes as an occupant who is absent for any other reason,” Alito said.
I think you are right. They can't search a home without a warrant just because a person isn't home. But if one occupant consents, and nobody is there to object, then they can search. Be careful who you live with.
