That depends on whether the cost to the looters of being shot so clearly outweighs the value of the stolen goods that the storeowner should do nothing, at least at the moment. He always has recourse to the police and the possibility that they might recover the goods.
但是，这是成比例的吗？那就要取决于打劫者被枪击的代价是否明显地高于被盗商品的价值，以至于店主应当至少在当时不什么也不做。店主总是可以报警并且可能索回商品。换句话说，当使用武力的代价过高时，武力就不成比例。
