Harvey finds a brand-new iPhone X in the men's room at the local Dunkin' Donuts shop.Harvey may take it home and use it,because the law is "a finder's keepers,a looser's weepers."

The law is not "finder's keepers, loser's weepers." In most cases, a person who finds lost property has a legal obligation to try to return it to the rightful owner or turn it over to the authorities. Keeping someone else's property without making a genuine effort to return it could be considered theft or another crime.
