Won’t matter at this point. Even if it turns out to be faked. It won’t matter. His base is that fucking stupid. The idea has been planted and it doesn’t even have to be true.
A faked shooting? Real Secret Service would have him protected on the ground not screen hugging him so he could pump his fist for the cameras with fake blood cap popped on his ear.
As much as I hate to admit this, it wasn't a fake shooting. The 'acting' was way too good to be faked. The mid-word 'stung in the ear' confusion slowly followed by the realization of what happened and the clumsy collapse to the ground are just too believable to think it wasn't real. That said, whether it was a false flag or not is another story.
