Anybody could claim that they were in their car at that time. Not at all surprised that Chapman is willing to just take somebody's word for it, as long as they say what he likes.
As for Benavides:
Mr. BENAVIDES - Later on that evening, about 4 o'clock, there was two officers came by and asked for me, Mr. Callaway asked me---I had told them that I had seen the officer, and the reporters were there and I was trying to hide from the reporters because they will just bother you all the time.
Then I found out that they thought this was the guy that killed the President. At the time I didn't know the President was dead or he had been shot.
I was just trying to hide from the reporters and everything, and these two officers came around and asked me if I'd seen him, and I told him yes, and told them what I had seen, and they asked me if I could identify him, and I said I don't think I could. At this time I was sure, I wasn't sure that I could or not. I wasn't going to say I could identify and go down and couldn't have.
Mr. BELIN - Did he ever take you to the police station and ask you if you could identify him?
Mr. BENAVIDES - No; they didn't.
