Do we know that? I don't think we do. When a person's computer (or smart TV, or smart fridge, etc...) is compromised and used as part of a botnet, they don't get criminally charged.

You're right - it is a complex situation based on intent and negligence - requiring a decision by a judge. As it has been since forever.

None of which is changed by replacing a buzz saw with an agent.
