There would be rioting, looting, destruction not in Pennsylvania and everywhere else? It's a tricky sentence to reverse.
Best of was that the sniper was such a good marksman that he managed to nick Trupms ear (whilst his head was moving) to make it look real.
Apparently they were kicked out of the school shooting club after one visit, as they were so bad they hit a target about six lanes up from the one they were actually aiming at, and were felt to be so **** they were a danger to others. As mentioned earlier, rather than a conspiracy I reckon it's another case of Hanlon's Razor “never attribute to malice that which is adequately explained by stupidity.” The Americans struggle to accept that their Security Services aren't all that the media and movies make them out to be.
It's obvious what happened. You can see Trump apply the fake blood to his ear before he ducks for cover.
