I don't agree with the logic that a larger caliber round would be used.  How much sense would it make for another sniper being used to frame this kid to use a totally different ammunition type?

 The cell phone audio is compelling, but having heard tons and tons of those videos I can say they are very inconsistent.  The noise cancelling alone has made multiple shots, made by me, sound like they are from two totally different firearms.  IF we had good audio from Trump's perspective that would be ideal.

 Also, if there is a second shooter, why the hell would they be right in naked-eye view of all those humans there?  Logic would say to put the second shooter in a considerably more concealed position than what is proposed here.  

 I get the idea of two shooters, two similar if not identical ammo/weapon types, but why in plain view?  And no I don't think the "everyone is too stupid to figure it out" logic is sound.

 The problem with that is the human head is not 90 edge and the ear protrudes.  The nose-point method assumes Trump is looking directly at the shooter at the exact time the shot is fired, but he could be looking as far as 10 or more degrees to either side and still have his ear hit.  

 A one degree difference at the point of impact can be hundreds of feet apart at distance.  

 It's a proven science used for centuries by sailors, and today by pilots, snipers, even cake decorators, but acknowledging that won't happen.

 I still don't think a second shooter would be placed in plain view on a roof like the video calculates with hundreds of people around that can see it.  

One degree, blahh,blahh,blahh,, IF there was more than one shooter and IF they weren't in each other's pocket,  then,, finish it yourself.

 Yeah like I said, acknowledging basic math isn't going to happen.

 You can't tell the exact location of a shooter based off the human nose because the ear can be hit from multiple angles, even from the front, as it protrudes from the head.  Angles increase in degree with distance.  At what angle was his ear shot?  Was it exactly 90 degrees?  How can the human nose prove that?  

 The problem here is there are only a few vantage points in that area to make that shot and the video available doesn't give a good enough indication of primary position at point of contact.  If anything the point of impact behind Trump COMBINED with another exact point of reference is needed to "draw a line" to a location.  A single end point is guesswork at best.

 Millions of humans are watching the videos of the shooting and one guy on a motorcycle forum figured it out.

Twenty minutes,, inexcusable.

So You say. Any honest attempt at figuring this out would include a reenactment with every bullet strike and injured person position studied. The number of Oopsies,, just a little oversight,, we should have done better events is staggering.
I say ,done right, the Nose points to the shooter ,the size of the strike zone in baseball.

Trump's nose would point to the jumbotron with the chart he was describing
If he had been looking at the shooter, he'd have ducked a bit sooner
