This doesn't just prevent overreach, it prevents any collection. Also known as "obstruction" (and possibly "destruction").

So you want the police to start physically impounding property, instead of just getting the data it had a warrant to collect? How is that preventing overarch? It seems to be demanding it!

(If it were me) Yes! It's annoying as hell to have them haul off my workstations but I would much rather them seize the locked and encrypted data while legal has time to do the due-diligence on the warrant and come up with a plan for compliance.

I keep my head above water so I really don't really care if the police can access the data. I do have a problem with the raid giving them access to data well beyond the scope of their warrant and relying on the courts to pare it down after the fact.
