I guess that if you have PII on your device/machine that is extra sensitive, you probably also have a decent size company behind you, in which case you could refuse until the legal team gets to you and challenges the warrant or asks for an actual forensics team to do the investigation - of course you may just give it up and let the company deal with the fallout after. If as another commentor has said, it is based on location, rather than specific devices, then I can't see a lot of these warrants holding up once it affects someone with a lot of classified stuff on there. Eg. You pop round a friends house from work, you do contracting work for the MOD and have your work laptop with you, turns out your friend is involved in some financial "bad stuff" and you happen to be there.
