I have been shooting firearms for 20-25 years. I would not call myself an expert's expert, but it sure appeared to me to have been an easy series of shots for Oswald to have taken.
I was most surprised by how small the area was and how close Oswald and Kennedy were to each other.
So have I. The first thought that popped into my mind when I stood at the window and looked down was what an easy shot it would have been. I have read the Warren Report Summary, and Posner's and Bugliosi's books also, and believe that Oswald acted alone. But I know that's probably not the majority opinion on FR.
