Rule of Law:

The critical element in a reasonable search is not that the owner of the property is suspected of crime but that there is reasonable cause to believe that the specific 'things' to be searched for and seized are located on the property to which entry is sought.

Rossconcluded from the historical evidence that the permissible scope of a warrantless car search "is defined by the object of the search and the places in which there is probable cause to believe that it may be found." The same principle is reflected in an earlier case involving the constitutionality of a search warrant directed at premises belonging to one who is not suspected of any crime: "The critical element in a reasonable search is not that the owner of the property is suspected of crime but that there is reasonable cause to believe that the specific 'things' to be searched for and seized are located on the property to which entry is sought.

In sum, neitherRoss itself nor the historical evidence it relied upon admits of a distinction among packages or containers based on ownership.When there is probable cause to search for contraband in a car, it is reasonable for police officers-like customs officials in the Founding era-to examine packages and containers without a showing of individualized probable cause for each one. A passenger's personal belongings, just like the driver's belongings or containers attached to the car like a glove compartment, are "in" the car, and the officer has probable cause to search for contrabandin the car.

Application:

To require that the investigating officer have positive reason to believe that the passenger and driver were engaged in a common enterprise, or positive reason to believe that the driver had time and occasion to conceal the item in the passenger's belongings, surreptitiously or with friendly permission, is to impose requirements so seldom met that a "passenger's property" rule would dramatically reduce the ability to find and seize contraband and evidence of crime. Of course these requirements would not attach (under the Wyoming Supreme Court's rule) until the police officer knows or has reason to know that the container belongs to a passenger. But once a "passenger's property" exception to car searches became widely known, one would expect passenger-confederates to claim everything as their own. And one would anticipate a bog of litigation-in the form of both civil lawsuits and motions to suppress in criminal trials-involving such questions as whether the officer should have believed a passenger's claim of ownership, whether he should have inferred ownership from various objective factors, whether he had probable cause to believe that the passenger was a confederate, or to believe that the driver might have introduced the contraband into the package with or without the passenger's knowledge. When balancing the competing interests, our determinations of "reasonableness" under the Fourth Amendment must take account of these practical realities. We think they militate in favor of the needs of law enforcement, and against a personal-privacy interest that is ordinarily weak.

Finally, if we were to invent an exception from the historical practice that Ross accurately described and summarized, it is perplexing why that exception should protect only property belonging to a passenger, rather than (what seems much more logical) property belonging to anyone other than the driver. Surely Houghton's privacy would have been invaded to the same degree whether she was present or absent when her purse was searched. And surely her presence in the car with the driver provided more, rather than less, reason to believe that the two were in league. It may ordinarily be easier to identify the property as belonging to someone other than the driver when the purported owner is present to identify it-but in the many cases (like Ross itself) where the car is seized, that identification may occur later.
