I have no doubt there was a shooter on the water tower, who well may not have been able to get a shot off. But how would anyone know that person to be a FBI sniper?
I will admit, I would not be the least bit surprised if it is true. FBI investigating the FBI, now that sounds about right.
FBI snipers have been at just about every event of chaos in the USA for decades, from Ruby Ridge, Waco, to no doubt Trump's assassination. Had a relative via marriage that was a FBI sniper. He has seen some sh*t.
But I would pose the following: if a FBI sniper was there to kill Trump, and he fired, Trump would be dead. PERIOD! So, while he may have been there, my guess, if that was the plan, it was probably coordinated to fire X minutes into the rally. The kid being rushed because he was discovered could have thrown the choreographed assassination into flux.
We will never know the truth on this, unless the FBI sniper comes forward and confesses, and do not hold your breath.
No one here will know the truth.
