I feel like there's a lot of room in "imminent" - I wonder what precedent has to say.
E.g. probably if two guys are arguing in physical proximity and you're shouting for guy A to shoot guy B, that counts.
But maybe if you tweet, "hey everybody, go kill that guy", it's not imminent/directed enough?
I only say this because I feel like I'm pretty often surprised by how high the standards are for applying some laws, despite the title/brief description of the law (of course as a rule, high standards are good here, but sometimes they can feel so high that the law has no teeth).
