From an anon:
“St Johns Reform Church on Evans Rd.
GWP poster suggested a dollar general roof at 560yds out..
Looked where I though he was talking and right across the street is the church with a tower that has a perfect line of sight that runs from the church tower and between the water tower and the Crooks sniper position right into the full venue. No obstruction. Less than a half mile shot which would be easy for any well trained sniper.“
