He had the means (the rifle).
Information, the route of the motorcade was published days ahead of time showing it passing by his workplace.
Opportunity, had the 6th floor to himself and set up his sniper nest with time to spare.
Circumstance, Kennedy vetoed having the bullet proof bubble put up and was unable to move out of the way of the 3rd shot because of his back brace.
Great post. Especially impressed with your comment about the back brace. You’ve clearly done your research as not many people know about how that really contributed to the murder. Bravo.
