I think we can all be thankful that, armed with a device that produces a cone of fire from one end, Heathcliff uses it to avoid dog owners instead of incinerate dog owners.
We know, after all, that Heathcliff just won't be undone (this is axiomatic) and has access to terrifying weapons (such as the Meat Robot) that are capable of laying the city to waste. For all we know he has a helmet that says "Armageddon" on it. Clearly, he can freely get away with murder if he wishes, as he is the de facto government.
