This conventional formulation, though, omits an important limitation: In basically all states, you can use nondeadly force to defend your property—and if the thief or vandal responds by threatening you with death or great bodily harm, you can then protect yourself with deadly force. So in practice, you can use deadly force to protect property after all, if you're willing to use nondeadly force first and expose yourself to increased risk.
Sounds reasonable.
