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 8 citing decisions cite the case generally; a passage count includes only decisions quoting that exact language verbatim.
“Probable cause is made out when the facts and circumstances which are within the knowledge of the officer at the time of the arrest, and of which he has reasonably trustworthy information, are sufficient to warrant a [person] of reasonable caution in the belief that the suspect has committed or is committing a crime. The question we ask is not whether the officer’s belief was correct or more likely true than false. Rather, we require only a probability, and not a prima facie showing, of criminal activity. In determining whether probable cause exists, we apply a totality of the circumstances test.”
