Say I am talking to someone I know or suspect might be arrested if they have contact with law enforcement. I don't particularly want them to be arrested: maybe I know they didn't do whatever it is they are suspected of. I also happen to know that there are police to the north, but not to the south.
Can I tell them, "Hey, when you leave, make sure to go south, because the police are to the north and might catch you"? Or would that be something like conspiracy to resist arrest, interfering with an investigation, or some kind of generic aiding and abetting?
Does it matter if everyone involved is just chilling, versus if the police are actively chasing this person and they are actively fleeing?
This presumably differs by state; I am interested in answers for any state, and for federal law enforcement if they are somehow different.
