We all have seen the LEO on the roof power-washing the shooter's blood/DNA off the roof, as Rep. Higgins noted "cops would never do that," but there's more.
The FBI showed what was ostensibly the shooter's backpack. The trouble is, what they showed was brand new, teal green, and pristine. What the shooter left on the roof was not so pristine, but black and had at least one aftermarket attachment (a plastic clamp, it would appear):
What would such a clamp have been for, and why didn't the FBI want the public to have available only a false image of the crime scene?
Also, an apparently Photoshopped image of the shooter aiming his rifle on the roof shows him wearing shorts and only a gray T-shirt, which, we've been told was from the Demolition Ranch. Note how, in the aiming photo (mid-below), the T-shirt is curiously-distinct, razor sharp contrast to the rest of the image. Below, in the date-and-time-stamped image, the image seems somewhat edited near the shooter's chin, right shoulder and as it involves the medic's gloved, right forearm. The upper of those three images shows why--I believe--we've been shown Photoshopped images.
Accidentally, LE let a bodycam image slip through that discloses the shooter was not wearing only the T-shirt, but had some kind of shoulder apron, as well. I presume he wore that to hold extra magazines. (I believe it may well have been the plan for him to "hose down" the podium and bleacher area with gales bullets from which many people would not escape alive--least of all PDJT.) If LE would toss such a magazine holder aside to obfuscate the crime scene, would they not as easily remove one or more weapons from where they might "tell an important part of the tale?"
One can quickly and easily understand why such evidence of extra magazines would need to be removed by allegedly complicit law enforcement. In any event, there must be "good" reason for all this Photoshopping.
