Who knows? maybe some noise made Oswald hesitate. You ever shoot someone head on? unless you come up with something better, then sit down.
Yes, I have shot someone head on. Don’t tell me to sit down. After what you’ve seen the Intelligence community and our Department of “Justice” do to Trump and his supporters, I’d put nothing past them anymore.
I also notice that you didn’t address the bizarre actions Oswald took after killing Kennedy and getting away.
