This is just dumb conspiracy theory shit.
Bullet trajectory showed Trump would be dead if he didn't turn his head last minute. That slight turn allowed the bullet only to glance his ear. That same bullet then hit some in the crowd behind him. He then fliched a bit, and the other shots that were still aimed at the initial first spot all missed and hit the crowd behind him.
There is such a slim chance that was all planned. Trump was directly in line of fire and could have easily been killed if this was just a stunt. They'd never risk that.
Don't spread shit rumors in a time when there is plenty of real shit in front of your eyes to be angry about.
That's what our 2nd amendment right is here for. If you have an immigrant visa, you can legally buy a gun. They should be aware of their rights to protect themselves.
