Is there any reason to believe this isn't completely too late? 24 hours after the ICO announced she was <i>seeking</i> a warrant, crates of documents were observed being unloaded from Cambridge Analytica's building. The offices weren't actually raided for an entire working week! Surely, with that kind of notice, they'd be idiots to leave anything incriminating lying around?
How useful is a physical search warrant when much information is stored in the cloud? Wouldn’t it be more useful to procure one for the cloud providers the company uses?
