It’s difficult not to love an opinion that contains this paragraph:
Heraclitus famously said that one never steps into the same river twice. What he meant was that one never steps into the same water; the river is the same, even though its substance is always changing. And so a conspiracy can be the same even if all the acts committed pursuant to it are different, because it is the terms of the agreement rather than the details of implementation that determine its boundaries.
Federal prosecutors love conspiracies more than Oliver Stone. Prove an agreement between A and B to further an illegal end, and you can bring in all sorts of stuff against A that she didn’t actually do (B did). And you only have to prove a constructive agreement – not an actual one.
