Facts of the Case:
Agent Coleman was informed by police in Hawaii that a package was going to be sent there with weed inside. The police sent the package and they followed the guy who picked it up to his apartment.
While one officer went to get a warrant, the police saw Acevedo walk to his car and place a brown bag into the drunk. They feared that evidence would be lost so they stopped him and searched the car without a warrant
A warrantless search of an automobile-based upon probable cause to believe the vehicle contained evidence of a crime in light if exigency is permissible
You don’t get to search a closed container just because it ends up in a car.
If the police have probable cause to search a car they have probable cause to search all of the containers within.
However, their search must be limited to that specific container, unless they have probable cause that the car itself contains contraband too.
If there is probable cause either to the car or the container you may search without a warrant
If this happened after Acevedo the second the closed container touches the car, they have probable cause to search the container
Acevedo rule: Chadwick was right with regard to containers in the world, but once a container is inside of a car, it is like a car.
