If you put a safe in a storage locker, the police could gain access to the safe and crack it by serving a search warrant on the storage facility, without ever notifying you -- and in fact they could get a companion gag order to prevent the storage facility from telling you or anyone else that they had done so.<p>If the service were willing, the police could even gain access by just asking. In that case, you might have a legal claim against the service, but not against the cops.<p>That&#x27;s probably the best analogy to data in cloud services.
