This would seem to be part-and-parcel with any attempt to create a media shield policy or law. You can’t provide a special immunity to the press without defining who the press is.
Ordinary citizen do not have immunity from searches when the government obtains a valid warrant. If my business, though no fault of my own, comes into contact with a criminal, the government can get a warrant to obtain information that would help them convict the criminal.
What shield policies and laws do is exempt the press from being searchable under the same circumstances as an ordinary citizen. Exempting the press may be justifiable but it still requires defining who qualifies for the exemption.
