This has extended far beyond just drugs in cars. There have been a number of stories done of cash forfeitures in Atlanta airport. They pull people aside as they are boarding and take their cash. Never consent to searches. Make them produce a search warrant. Miss your flight and protect your 4th Amendment rights.
Those Boxes were opened in a warrantless search in 2021 and $86 million dollars worth of coins, cash and other personal belongings was seized and only a few people have gotten their items returned and that was after they sued the FBI.
Some of the rare coins seized turned up for sale at rare coin auctions.
So having a safe deposit box makes you a drug dealer ?
