hiring a hitman is a complicated game theory problem because the hitman always has the option of just taking the money and calling the cops. you have to convince them that you are capable of hiring another hitman to come after the first hitman, but the very act of trying to hire the first hitman indicates that you don't have a second, more reliable hitman ready to go. so i guess the moral of the story is don't be a landlord. https://www.latimes.com/california/story/2024-05-07/landlord-sentenced-20-years-in-prison-in-murder-for-hire-plots
