If the something in question is a crime though, then that's called a conspiracy and there are laws against that. The legal difference in this case is the overt act, where one participant takes a criminal action beyond speech. Conspiracy is hard to prove in court, but that doesn't mean that I can say whatever I want and be completely absolved just because the action was not taken by my own hand.
