first of all, you are an angle if you are able to go back to that site! 
I took this shot from your footage timestamp 1m10:
these rectangles indicate two areas of interest that are very important:
the top rectangle is where the JCB hydraulic lift was. if you could take a couple of shots looking straight down, that would be great.
if your drone is gps coordinates enabled, and you could share the gps coordinates and bearing while taking these shots, that would be great too!
the second rectangle is where Trump’s podium was located.
also a shot looking vertically down, possibly with gps coordinates and bearing.
if gps coordinates and bearing are not possible/available, that would not be a big issue, but it would make the alignment of the pictures as a ground overlay easier.
the second thing would be the following:
the rectangle starts something like 2-3 yards over the barns where the snipers were located behind Trump and stretches to halfway the barn in the right bottom of these pictures.
if you could zig-zag slowly from one diagonal corner to the other (e.g., if you would start at the orange dot you would fly to the white barn along a straight line looking as vertically down as possible. at the barn you move a little towards the AGR site and you fly as parallel as possible to the previous strip to the barn where the snipers were located, etc.
it is best that there is a little overlap between each strip such that these can be glued/mapped to one another.
best fly at a fixed altitude (there are electricity lines and poles, all over that place, whatever height you feel comfortable with is fine)
the number of strips does not really matter and depends on the angle of your camera and the height from which you look at the ground. the smaller the distortion due to wide angle view, the better… the number of strips I drew in this picture does not need to be the number of strips you fly your drone, he… as long as the location of the JCB hydraulic lift is included fully in a single strip, I am happy
this was the line of fire:
if you could drive or fly nearby that building in the oval and look for a couple of bullet holes or freshly painted or repaired areas, that would be great…
bullets do not necessarily stop where they hit something and may follow through, and that building lies in the direct line of fire…
about the high building at the parking lot, I expect bipod or tripod marks at these stars:
if you could take a closeup of the area in the rectangle to see whether there are some marks of a person lying in wait, that would be great too.
and should you be able to look at the rally area from right above these stars, thus close to the roof looking towards the rally area, that would be great too!
BigTim pointed out that in the video that was taken by James Copenhaver, they could see a head popping up between two ventilation pipes on top of the roofs. that may have been these pipes that you captured in your video at 0m34s and 0m45s:
(these are 3 pipes in total. it is likely that the head may have popped up between the pipes in the first image, or a combination of the pipes of both images…)
when your drone looks at the rally area, could you also take a shot where these two pipes are in view too?
many thanks!
