With the poisoner perk from the pickpocket tree, do you get a bounty for killing people?

"Reverse pickpocketing a poison using the Poisoned perk does not count as a crime, even if the magical effect of the poison (e.g. "damage health") would otherwise be considered a criminal act if applied any other way. This makes it entirely possible to kill or weaken innocent enemies, right in front of everyone, without incurring a bounty."

No, successfully planting enough poison on your target to kill him/her will not create a bounty .If you fail in your attempt to reverse-pickpocket a poison onto the target, you will receive a bounty. Furthermore, if you successfully plant poison on the target, but not enough to kill them, they may hire thugs to come after you. This will not put a bounty on your character.
