While I tend to agree with the main point of the first post, I think that often times we can create conditions where “luck” becomes more likely to happen. The limited time that the assassin apparently had to plan his ambush made things more difficult. Especially for him to “cover his tracks.” However, consider the items he managed to get accomplished in order to be able to get three shots off before anyone could stop him.
1. He managed to retrieve the rifle and sneak it into the TSBD without any apparent suspicions being voiced before the assassination. This is even though he didn’t drive and had to hitch a ride from BWF.
2. He planned his ambush to be from behind and above the target. This gave him not only the element of surprise, but also maximized the time he would have to fire multiple shots.
3. He managed to find and select a position that was visually well shielded from both outside and inside the TSBD. While sitting on the box seat, he was also able to stay out of sight of the SS agents as they approached the TSBD on Houston Street by simply sitting up straight. The boxes in the window would have made it more difficult for any of the SS agents to see him even if they had looked back at that window during the shooting. And keeping his position essentially initially undetected by LEOs he was able to then have a reasonable chance to escape after the assassination.
4. This position was also well selected for having a “kill zone” where the target was moving almost directly away from him. This substantially increased his chances of hitting the target.
5. His ability to act calm and blend in with other people after the assassination helped his escape efforts (for a while). This was lost after the Tippit murder and all the frantic police activity in the area and subsequently led to his capture.
