Mr. CURRY - I said what was that, was that a firecracker, or someone said this, I don't recall whether it was me or someone else, and from the report I couldn't tell whether it was coming from the railroad yard or whether it was coming from behind but I said over the radio, I said, "Get someone up in the railroad yard and check."
And then about this time, I believe it was motorcycle Officer Chaney rode up beside of me and looking back in the rear view mirror I could see some commotion in the President's car and after this there had been two more reports, but these other two reports I could tell were coming behind instead of from the railroad yards.
I imagine Curry slowed down somewhat after hearing shots and checking the rear view. The Limo actually drew ahead of Curry's car just after the underpass. The Limo itself was not going as fast after the final shot as they portrayed, in fact years ago, I worked out that Usain Bolt would have beaten the limo to the underpass from the final shot mark. Which made sense in the end, as Jackie would have slid straight off the rear of the waxed trunk if the limo accelerated too much.
