$-$CloudLocker is a cloud storage and computing service provider.

$-$During a murder investigation, CloudLocker voluntarily provided police access to a

user's $($Tony$\text{'}$s$)$ stored files without a warrant.

$-$The police used the information from the cloud files to obtain a search warrant for

Tony's apartment, leading to the discovery of additional evidence.

$-$Tony is now arguing that the initial search of his cloud storage by the pilice,

facilitated by CloudLocker, violated his Fourth Amendment rights against

unreasonable searches and seizures.

actions. Consider the evolving legal precedents around digital privacy and the
