Multiple options for Trump that day ...do a,b,c, d...assassins were stationed at a,b,c,d,...for 12 hours waiting...when Trump showed up at the golf course the other assassins were relocated to other sites by an agency for future assignmenrs... it’s easy to figure out ... They are playing football.. cover everything...end run, down the middle,Jet sweep,statue of Liberty ..they have assassins everywhere Trump might show up .
In WW2 the Japanese had hidden snipers in ALL the trees.
It would make sense to have multiple assassins covering likely places that Trump would visit.
