 Mere moments after the shooting happened on Saturday, many leftists had already decided that the shooting didn't actually happen at all. Or it did, but it was planned ahead of time by Trump himself. He hired somebody to shoot at him. Or he pretended that the guy shot at him. The theory isn't exactly clear. The left cannot meme, and it also can't come up with coherent conspiracy theories, we've learned. But the basic idea, whatever the specifics might be, is that the shooting was staged.
