This whole thing was a hoax. See fake news.
Crisis actors and blanks were used. The "blood" was applied to Trumps ear by a make up artist posing as secret service when he was on the ground. The shooter is not dead, just a fictional character made to look like he was shot.
Remember the movie FX? Where a Hollywood make up artist special effects guy has to fake a murder. This was that.
3 less Trump voters.
