None of the 3 technically knew they were culpable in a larger illegal plan made by an agent. Has something like this occured already?
The world is moving too fast for our social rules and legal system to keep up!
Investigators would need to connect the dots. If they weren't able to connect them, it would look like a normal accident, which happens all day. So why would an agent call gigworker1 to that place in the first place? And why would the agent feel the need to kill gigworker1? What could be the reasoning?
Edit: I thought about that. Gigworker 3 would be charged. You should not throw rocks from a bridge, if there are people standing under it.
Two women thought they were carrying out a harmless prank, but the substances they were instructed to use combined to form a nerve agent which killed the guy.
Who's at fault when: Your CloowdBot reads an angry email that you sent about how much you hate Person X and jokingly hope AI takes care of them, only for it to orchestrate such a plan.
How about when your CloowdBot convinces someone else's AI to orchestrate it?
Etc
One guy scouts the vechicle and observes it, another guy is called to unlock it, and bypass the ignition lock, yet another guy picks it up and drives away, with each given a veneer of deniability about what they're doing.
This is why conspiracy charges exist.
I don't get a "oopsie tee hee" card.
