I think someone technically skilled enough to run a Sia host would also be skilled enough to know how to delete delete a specific file off their hard drive. Sia could even provide a UI to make that easy. Though if Law Enforcement has access to the client's encryption keys, I think chances are it'd be way easier for them to just issue a delete command to the Sia network directly.
