Because Oswald was silenced before he could answer questions.
Oswald was in law enforcement custody from mid-afternoon on Friday until Sunday morning. He was interrogated during much of that time by the Dallas Police Department, the Dallas County Sheriff's Department, the FBI, and even a Postal Inspector.
And not a single word of it was recorded
I never bought Oswald as the lone shooter. In fact, I'm pretty sure he didn't fire a shot at all. Regardless, you will NEVER convince me that the fatal head shot came from behind Kennedy and not the right front (grassy knoll area).
I'm actually going to the museum on Friday for the 50th anniversary. I'm looking forward to it. I've been once before but I was 10 and don't really remember too much of it.
