Every man has the right to life, liberty, and the pursuit of happyness. The pizza delivery man was defending his right to life. Pizza Hut essentially says to him you can’t do that; it’s better that you be shot than that you defend your right to life.
As for your cop story, it’s a non sequitur. You argue against the pizza delivery man defending himself and follow that up by asserting the cop has no right to defend the defenseless. By your own words, American citizens are to be left at the mercy of thugs and gangsters and terrorists. Were we to follow your reasoning, those of us who were not deprived of life would soon find ourselves without liberty and unable to pursue happyness.
