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 219 citing decisions cite the case generally; a passage count includes only decisions quoting that exact language verbatim.
“... A Parole [sic] revocation proceeding is concerned not only with protecting society, but also, and most importantly with rehabilitating and restoring to useful lives those placed in the custody of the Parole Board. To apply the exclusionary rule to parole revocation proceedings would tend to obstruct the parole system in accomplishing its remedial purposes. There is no need for double application of the exclusionary rule, using it first as it was used here in preventing criminal prosecution of the parolee and a second time at a parole revocation hearing. The deterrent purpose of the exclusionary rule is adequately served by the exclusion of the unlawfully seized evidence in the criminal prosecution.”
