More like a dog. Person has no responsibility for an autonomous agent, gun is not autonomous.

It is socially acceptable to bring dangerous predators to public spaces, and let them run loose. First bite is free, owner has no responsibility, no way knowing dog could injure someone.

Repeated threats of violence (barking), stalking and shitting on someones front yard, are also fine, and healthy behavior. Person can attack random kid, send it to hospital, and claim it "provoked them". Brutal police violence is also fine, if done indirectly by autonomous agent.
