Study notes for Maryland v. Garrison: professor notes, cold call prep, exam angles, and memory aids.

A search warrant is valid, and evidence obtained is admissible if officers reasonably believe the warrant authorizes the search, despite later revelations of a mistake.
Professor Notes

In Maryland v. Garrison, the Supreme Court addressed a critical issue regarding the validity of a search warrant under the Fourth Amendment. The case revolves around the execution of a search warrant intended for a specific unit, but due to a lack of clarity in the description, police inadvertently searched an area that included multiple units. Professors often emphasize that the Court's ruling highlights the importance of police officers' reasonable belief in the search warrant's scope, even when later discoveries reveal that the warrant was overly broad. It raises significant discussions on the balance between officer discretion and the protections against unreasonable searches.
