That section does not seem relevant. That’s for government seizures of attorney work product.
See:
Work product materials are defined as materials (other than things criminally possessed or used as a means of committing a crime, see, e.g., U.S. v. Hunter, 13 F. Supp. 2d 574, 582 (D. Vt. 1998)
The section of law cited in the warrant is 18 USC 2721 and context makes clear it’s talking about the newspaper employee’s false certification as to one of the enumerated reasons in section (b)(1)-(14).
Which one of those do you contend applies to newspapers?
This is also not a case of journalists reporting information received unwittingly from a third party who obtained it illegally. That would not be a crime as far as the newspaper is concerned.
Rather, this is a case of a newspaper employee falsely certifying a government form to illegally access records firsthand.
Also, the newspaper admits to police it falsely certified it’s request for information.
