Do we know where Trump was at the time of the supressive fire? I've seen it said that he was 300-500 yds away, I've also seen it reported that the advance guard was two holes ahead. If they were two holes ahead on 5, and Trump was on hole 3, the shooter did not have line of sight yet. I've seen no indication this was a quick draw spray and pray thing.
Looking at google maps, and an map of the golf course, the north side of hole 5 is on the border of the club, up against a storm canal. Much more likely to have the shitty chainlink the pics show than the hedge and what looks like a wall that borders the east side of hole 6. Depending on where in that north treline you are, you are 318-561 meters from the green on 3. Which kinda fits reporting. Parts of that tree line has a sight line on all of Hole 4, so you could watch the tee off and pick a shot. There's also a parking lot where you could park, and get right into the trees without being seen, although that would be pretty ballsy, as to exfil you'd have to drive around the county jail. Public road, but man, you gotta get out fast.
