Most-quoted passages
The sentences later courts lift from this opinion, ranked by how many decisions quote each — the parts of the opinion doing the work. These counts are smaller than the citation total above because most of the 11 citing decisions cite the case generally; a passage count includes only decisions quoting that exact language verbatim.
“"[T]he analysis of whether a police investigation should be deemed a search and therefore subject to fourth amendment restraints must weigh the reasonableness of one’s privacy interest in the instrumentality, and the particular area of the instrumentality upon which the VIN is inscribed, and not just the reasonableness of the privacy interest in the number itself. Thus, while the examination of a VIN, inscribed on the dashboard of a car which is in plain view of a policeman *** looking through the windshield from outside would not be a fourth amendment search because it is not a 'prying into hidden places for that which is concealed’ [citation], by the same standard the examination of a VIN which can be observed only when a policeman has opened the door may well constitute a search of that portion of the vehicle otherwise concealed from public view. Although one’s expectation of privacy in the number may be no different, it is surely a matter of common sense that one’s expectation of privacy in that which can be seen from outside the car is significantly different from that which can be seen only when the door has been opened. Otherwise, why bother to put things in the glove compartment, under the seat, or, as here, behind the seat and out of the view of passers-by? We therefore reject the State’s contention that one can have no reasonable expectation of privacy in a VIN, regardless of its location on, or in, the vehicle, or the circumstances of the police investigation.
