ELI5: How hard is it for a sniper to shoot a moving target? (I'm thinking Kennedy)
gpt
I mean, hitting a moving target is always difficult. That said, Kennedy was moving at a very slow and mostly constant speed. In addition, the book depository wasn't really that far away. According to Google, it was only like an 80 yard shot. Further, all of the noise from the parade meant that no one even noticed Oswald was shooting until Kennedy got hit; he missed his first shot, and then was still able to line up another like nothing happened.

So whether or not Oswald really shot Kennedy (I don't feel like getting into conspiracy theories), the alleged shot was totally plausible, and could have been done by just about anyone with moderate skill. It wouldn't have taken a professional sniper or anything like that.
