Seems pretty straightforward to me. If the customer set the agent in motion, the customer is no less responsible for the damage than someone that (as i think Cal Newport said) ties a weedwacker to a dog. It’s reckless.

If they were sold a product that claimed to be safe, they could in turn sue whoever sold it to them. Jeep’s insurance wouldn’t pay someone I crashed into because of defect in my jeep, but I could in turn sue Jeep for my legal trouble.
