Eh. There is a big difference between an investigation ( as one sees in most American cinema hence why this particular phrasing is likely chosen ) and a fishing expedition, where LEOs go through data they in likelihood should not ( and to make it more annoying -- are highly unlikely to delete once done ).

I am saying this as a person who got LEO request for JUAN no last name and no other identifiers. As you can imagine, some of us are not amused by such requests.

edit: Location is much, much more telling than basic name and address.
