It's all a staged program, first of all an assassin is trained to shoot and he/she will not miss the target no matter what and when you hire someone to assassinate such a hyped individual ofcourse you are supposed to hire the top notch shooter. The shooter missed the shot even though Trump was barely moving.
Secondly, the bullet should have pierced his ear but it did not, he just sat and put the blood to his ear so it looks like he was shot. A selfish prick like him would have eloped from the stage right after the incident, rather he chose to stand still and wave even though there could been a second bullet piercing his ugly skull.
Thirdly, what we live in 90s still? That the whole perimeter was not inspected before the arrival of the formal president? No security camera footage? No satellite footage?
It's all a political propaganda, so the majority becomes emotional about the attempted assassination and vote him out of sympathy.
