Final answer:
Officers may usually only seize items listed in the warrant, per the Fourth Amendment. However, they can seize unlisted items if they are in plain view during the search or if there are exigent circumstances.
Step-by-step explanation:
The statement that officers may only seize items which are listed in the warrant is generally true, but there are exceptions. According to the Fourth Amendment, a search warrant must be specific regarding the place to be searched and the items to be seized. However, there are circumstances where officers can seize items not listed in the warrant, such as if the items are in plain view and it is immediately apparent that they are evidence of a crime, contraband, or otherwise subject to seizure.
Additionally, if officers are lawfully in a location on the basis of the warrant and discover evidence of another crime in plain view, they can seize that evidence as well. This is alongside the situations where a warrant is not required, such as with consent, exigent circumstances, or lack of a "reasonable expectation of privacy".
