If my wife listens in to me and my droogs plot the murder of someone, and never turns me in or says anything to the cops, she will be an accessory and do the same time ... even if we don't actually carry through with the deed. It's called conspiracy.
That's the law.
Aiding and abetting is against the law. Facilitating the commitment of a crime is against the law.
