I think the elevation question would be close either way - wondering more about the azimuth angle and whether the window shot aligns with the collateral human death and injury, plus the hydraulic lines of the speaker lift.
“...wondering more about the azimuth angle...”
The shooter’s body, backpack and rifle were near the east end of the low building. (Trump’s podium is east of the main crowd). From what I can tell from Google Earth that would have the shot going pretty much parallel to the front of the podium which matches (as far as I can tell) a shot at Trump. Although the big screen is a factor which I can’t tell from the various photos.
And it is probably just the idiot media, but they are all showing the shooter’s location as being near the WEST end of the building. That does appear to be where he was when the cell phone video saw him and the people are pointing.
And I thought he climbed up on the east side of the building. I guess he could have crawled to the west end trying for a better shot, but then moved back east for what ever reason. To be behind the tree so the snipers couldn’t see him?
I don’t know. I guess if he had 20 minutes to hang out on the roof he could do whatever he wanted to.
