Actions speak louder than words. He was around tons of looters (that’s what the people he was talking about were doing, when he said that) that day. Why didn’t he ‘shoot rounds’ at any of them, if that was his plan? He had all the opportunity in the world.
That’s the question people making this argument can’t answer honestly, because the only honest answer is that what he did directly contradicts what he said.
Arguing that he planned to do something that he literally didn’t do, despite myriad opportunities, is just silly.
