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 35 citing decisions cite the case generally; a passage count includes only decisions quoting that exact language verbatim.
“Implicit in any conspiracy is proof ... that an accused agrees to participate in the alleged criminal activity.”
2 later decisions quote this exact passage“Without this common purpose, a conspiracy cannot be maintained.”
2 later decisions quote this exact passage“The essence of the offense of conspiracy is an agreement between two or more persons to commit an unlawful act. The agreement required for conspiracy can seldom be directly proved, nor need it be. However, a mere association between several alleged co-conspirators or their mere presence at the scene of the crime is not enough to establish that there has been a criminal conspiracy. Among the circumstances which are relevant, but not sufficient by themselves, to prove a corrupt confederation are: (1) an association between alleged conspirators; (2) knowledge of the commission of the crime; (3) presence at the scene of the crime; and (4) in some situations, participation in the object of the conspiracy. The presence of such circumstances may furnish a web of evidence linking an accused to an alleged conspiracy beyond a reasonable doubt when viewed in conjunction with each other and in the context in which they occurred.”
