The shooter was a patsy/diversion. The water tower was the high point to control the whole area. This was an op, just like Trump and Roger Stone raid they were tipped off.
Dip shit on roof didn't get 8 shots off, they came from woods and water tower.
This was not a SS "mistake" it was a planned hit, regular SS diverted to Biden event. Even some FBI/PROUD boys on team (loyal soldiers/compromised FM)
This was a thwarted attempt of the same play book when they took out JFK and tried with Reagan
