Jean Hill's affidavit stated:
"I thought I saw some men in plain clothes shooting back but
everything was such a blur and Mary was pulling on my leg
saying "Get down thery [sic] are shooting"."
And her testimony:
"Mary grabbed me and was yelling and I had looked away from
what was going on here and I thought, because I guess from the
TV and movies, that it was Secret Service agents shooting back.
To me, if somebody shoots at somebody they always shoot back
and so I just thought that that's what it was and I thought, well,
they are getting him and shooting back, you know; I didn't know."

Senator Yarborough smelled gun powder in Dealey Plaza, & wrote to Earl Warren:
"Immediately after the firing of the first shot, the thought immediately went through my mind that 'that was a rifle shot.' It did not sound to me like a firecracker or a pistol, though I thought of them too, or the possibility of a small bomb. Another immediate impression that I had, was that the cavalcade had slowed down, almost stopped. . . . After the second shot, I could smell gunpowder very strongly and the rancid smell of gunpowder stayed in our nostrils for minutes as we raced toward Parkland Hospital. This caused me some difficulty, as I'd never smelt so much gunpowder from three rifle shots, and I'd begun to think that perhaps someone had thrown a small bomb in the presidential car. . . ."
